not sure what to do

[five0addict]

got necrosis, yellowing, burning, and shriveling, my stems were real purple but theve started to look more green after a recent repotting. in a couple weeks into flower on an unknown strain.
right now all im feeding is foxfarm bigbloom 1/2 strength every watering (according to the mix for every watering of course) and 1/2 strength "western states" brand vitamin b-1 for my recent transplant.
it has .125% iron, .125% manganese, .125%zinc, .01% thiamine mononitrate.
my water is 6-6.5ph brita filtered tap water.
the tops are growing some bomb buds but my leaves are dying faster than there growing.
also looks like my thrips are coming back, is it safe to use neem around buds?? i have insect soap too would that be better?

Feed em...they want more food!

Well since no one has answered you I can give you some text book answers, but thats about it since I myself am a newbie.

Two problems I noticed. You said your tap water is 6.5 but what is the runoff after watering? This is what is important. The second problem is you said you are feeding with Fox Farm Big Bloom half strength. My guess is your plants are starving to death. The Big Bloom is used in addition to the Fox Farm Tiger Bloom product. You can use the Tiger Bloom only but just using the Big Bloom only will not be enough.

From what I have read neem oil can be used in flowering.

Also could you please post a full body shot of your plants please. Also what are your temps and the lights you are using? What is your soil mix? Are you using perlite in your soil because it sure doesn't look like it? How long did you veg for and how long have these plants been in flower?

sorry this is an outdated pic i will get another tomorro.

i started from a clone and vegged for 6 weeks, now im flowering under a 250w metal halide temps between 75-80 under the light, 50-65 at night. im using an all purpose potting soil. i havent checked my runoff ph scince repotting, ill do it next watering.
should i give a foliar feed?
ill stop by the hydroshop and pickup some tigerbloom

If your going to get something from a hydro shop, get cal mag plus or similar. I think you may find this beneficial to add to your bloom ferts.

 

[five0addict]

my runoff is a solid 6.5-7, good?
calmag+ instead of ff tigerb?
i upped the feed and tryed a foliar feed to hold over till next watering. also neem/safersoaped after i saw a couple bugs crawl out of the soil! bastards!

The fert your currently using has hardly any nitrogen. You got to have some for the plant to be able to function. The tigerbloom has some nitrogen which is good. You might try getting both tigerbloom and cal mag plus and mixing them together. Or, use the original fert you had and add cal mag plus. There is some nitrogen in the cal mag plus which would be beneficial. (not really much n) I think both the tigerbloom and original fert both lack calcium and magnesium so they both benefit from the cal mag plus.

Try keeping your ph closer to 6.

One very important thing to mention is I don't see a fan. This is very important. This might be why your stems look so thin besides the fact that this plant is under ferted. Also how are you getting any fresh air in your closet, this is also very important. Even just a little bit of fresh air just while the lights are on is better than nothing.

>calmag+ instead of ff tigerb?
No get the tiger bloom. Sproutco is just saying to give your plant a dose of calmag. I have never used the calmag product so just follow the instructions on the packaging or do a search on this forum. I usually just use epsom salts and give 2 tspns once during veg and another 2 tspns during flowering unless they need more, but calmag is the right way to go. Also do yourself a favor and pick up some ph up at the hydro store you will need it when using tiger bloom.

>my runoff is a solid 6.5-7, good?
Usually anything between 6-7 is good but I always try and shoot for 6.2-6.5, it seems to be the magic number for me. At a ph of 6 and I start to see some deficiencies and anything above 6.8 and I have problems also.

>i upped the feed and tryed a foliar feed to hold over till next watering.
what did you feed with, hopefully tiger bloom?

>now im flowering under a 250w metal halide
metal halide is good for veg but not for flower. I have no experience with metal halide I use a 250 watt HPS but I hear MH can be used for flowering, it will just take longer for your plants to finish. I have read about conversion bulbs. I know they make HPS to MH conversion bulbs, not sure about the other way around. I would check into this if I were you.

I have a question. Is there a reason why the fan is off during the dark cycle or can it be on 24/7?

 

[five0addict]

yea i got 2 fans, one sucking air from under the door and an big occilating fan at bud level. i have to keep the door cracked because the fan isnt powerful enough to overcome the pressure with nearly no exhaust. there would be no way to hold 75-80degrees a foot away from the light without those fans.
the dude at the hydro shop said i shoulda started with the tigerbloom then gone to the bigbloom, and doubts i need calmag (18$) because im using tap water. that and its probly overferting, this isnt a soiless mix. next grow will be, definetly! im sick of being so unsure!
my bulb is doin fine, im just starting out. dont got any money to spend on this but im sqeezing in what i can. my whole light setup cost me 50$ and that was a huge dent in the budget.
so ill try some epsom see if anything changes, cheaper than calmag+
i know the stems droop a little at night, idk if putting a fan on them in that flexible time is good or bad. my fans come on with the light.

 

[Guest]

Ok i was wondering cuz i have a cooltube light reflector that is cooled by a 265cfm Daytona inline fan that turns on when the light turns on but i have a seperate fan that circulates the grow room itself. that one is on 24/7. Is this ok? Its rated at 90cfm

 

[five0addict]

if your temps are ok i dont see why not.

Since they are starving for nitrogen, the quick solution might be to give them a full strength dose of veg ferts.

and don't listen to sproutco - he's an poser, who poses as a grower but dosen't grow - - BEWARE

And gives neg K for pointing this out

over 3,200 posts since MAY 2006???

heavy dose of ferts may kill it and high N will extend flowering

Plant looks very rootbound -- how long has it been in the pot? and you do let it dry out between waterings?

Yes I agree, that is what I have been telling you. Some people use big bloom along with tiger bloom and a lot of people just use big bloom the last couple weeks of flowering. Some people like me don't use big bloom at all. Some people just use big bloom all by itself but it was not intended for this purpose and you will most likely need to use more than what the instructions tell you. Besides that it is going to be more expensive if you use big bloom all by itself.

>that and its probly overferting, this isn't a soiless mix.
I guarantee you that this is not over ferting. It is not showing any of the classic symptoms of what over ferting looks like. It looks just like under ferting. Does your soil have any NPK (fertilizer added) check you bag and post the numbers.

Just put in 1 tspn of tiger bloom into 1 gallon of water and just water your darn plants with it. Personally I would do 2 tspns if it were me, but if you want to play it safe just use 1 tspn. Maybe add 1 tspns of epsom salts also. And dammit check your ph runoff every time you water. Next feeding then use 2 tspns of tiger bloom if you don't see any burning problems. I would feed every other watering if using 2 tspns or every watering using 1 tspn. Everyone does it differently and with different amounts. You will just haft to find your sweet spot. You plants might be able to handle a lot more than what I am suggesting but this should be a good starting point.

Also did you add any perlite to your soil mix, if you did how much did you add? This is very important because it dictates how often you can water.

wrong


tiktok420 and CJTK are both right on giving your plants a full strength veg formula now would be counter productive to say the least. If you give them anything give them tiger bloom. A couple of doses and thats it. As nutrient deficient as that plant is...it should taste great!!!

One product that you could look into as a N substitue in flower would be some of the carb products like sweet from botanicare or Technaflora has come out with a new carb product called Sugar Daddy that works great too. The lower nitrogen levels often found in flowering stage fertilizers are overcome by the use of SugarDaddy or Sweet; as carbohydrate, protein, and fatty acid synthesis is achieved vigorous growth rates are maintained along with the production of essential oils and the aroma value of flower buds and fruits.

Have a nice day

I'd say cut the thing in half, re-veg, and try again. For that much light you should be able to get much better. It might end up being more stress than it's worth, but could cut down on time to next (hopefully healthier) harvest.

Good luck!

[five0addict]

so the consensus shows N def. that sounds plausible.
i know the shop has Sweet, gotta love the name!
luckly they have all the best brands i hear about on here, guys definetly know whats up and im guessing they grow the med-grade buds for the local dispensery.

cut it in half!? dude if the buds didnt grow anymore, id still be happy. so dont worry, i will probly continue with this hobby, and do it right next time.

 

[sproutco]

Usually growers add about 100 ppm nitrogen with their ferts during flowering. This will keep the leaves from going yellow too quickly but yet not strong enough to encourage growth. If you want to try a low dose of n like this, get the fert numbers off the bottle of veg formula you have. We can enter them into the calculator in my signature below. If you can find the net weight on the bottle and total ml of the bottle, this will increase accuracy. Otherwise we will use the default setting of 1 and 1. The calculator will give you ppms of the fert solution at whatever strength in ml per gallon your using. If you don't know the type of nitrogen but have the total %, enter it once in either nitrate, urea, or ammonia but only do it once. The answer will be the same no matter which one you choose. I can help you if needed.

Sprout...your advice was to give full strength veg ferts.

For the past few months I've been looking at Sproutco's posts like he is an expert garderner, and if it weren't for doing more info on his subjects I might have even tried his methods.......well actually that's half a lie. Battery acid on plants is the silliest damn suggestion I've heard so far. Boron is pretty out there too....it just sucks for the new people coming here because they're already confused enough about how a weed plant grows, let alone this ridiculously complicated argument about boron. Silly.
