Possible Calc dif/result of 2hr blackout?

[Guest]

These 2 pics were taken on Day 29 of flower.

yesterday, the lights were out for 2 hours, right in the center of a light cycle. No signs of herm.

This girl has been fed chemical nutes (Miracle grow bloom booster) 3 times (1/4 dose), and for the most part has been hassle free. These just showed up today, and are all over the plant. Rust colored specs with browining on the edges of the fan leaves.

I am thinking calcium deficiency, so i should use some dolomite lime?

As always, any input is greatly appreciated.

What is mixed into your soil like dolomite lime and how long ago was it prepared? What is the ph of the miracle grow water once mixed? What is the type of soil? Does it contain peatmoss, perlite, vermiculite, or pinebark? Do you know the ph of the soil? What are your temperatures? Which leaves are being affected by the burn...new leaves or bottom leaves? More information gets a better answer.

Nothing has been mixed into the soil. It is Miracle Grow Potting Soil. i have a test kit somewhere so i will post the Ph with water as soon as I find it. The temps average 77-80 during the day, dropping to 75-78 at night. This is a 340 watt flouro grow in a 6 x 3 x 12 room. Additionally, this is only occuring on 2 of 3 plants. The unaffected plant is unfortunatly bagseed, but is looking heavily sativa. The other two are MMM #2, both of which I belive are indica.

The affected leaves are in the center of the plant. They are not new growth. In the past, they were a solid deep green. About 2 weeks ago i noticed several tiny white spots on the same leaves. I'm kicking myself for not acting on this then, but after I made sure it wasn't pollen, I dismissed it.

I haven't purchased the dolomite lime yet.

I hope that helps, and again. thanks a million

PS: I was considering chopping those fan leaves because they are blocking light from budsites beneath them. it seems even more tmepting now, should I?

Don't remove leaves unless dead. Miracle grow plant food is probably not the best thing to be using. It is mostly urea/ammonia nitrogen and little nitrate nitrogen. It's source of potassium may be potassium chloride and adding alot of chloride is not desirable. It probably contains no magnesium, calcium, or sulfur. It does contain n p k and micronutrients. Check your label to see if I am right. I would add 1/4 teaspoon magnesium sulfate/epsom salts plus 1/4 teaspoon powdered gypsum/calcium sulfate per gallon of water along with the mg plant food. You can get gypsum at a garden center (call 1st) and epsom salts at the drug store. This would make your fertilizer complete and add the needed mag.,cal., and sulfur. You will want to adjust the fertilizer water after mixing with an acid or base so that the ph is about 5.8-6 You can use this to do it: http://www.icmag.com/ic/showthread.php?t=31294&highlight=sulfuric+acid If you don't have a ph meter, you can use cheap ph test strips from the pet store in the aquarium section. Even if your soil contained dolomite lime, it is good to boost levels of cal and mag every 3rd or 4th fert. If I were to guess, I would say use mg plant food 15-30-15 at 3/4 teaspoon per gallon of water everytime you water. Hope that helps you.

its not good to use that weak of a dose because its hard to get that small of a dose per gallon of water sprout, what would be easier is just to use 1/2 teaspoon per gallon weekly and know you are giving it that much. 3/4 teaspoon is small

most people would give a little more than that and not to mention every water if they only water 2 times a week they wouldnt be getting enough... see what i mean?
by the looks it looks like hes not feeding enough. only using it 3 times at 3/4 dose..... not enough your plants look like calicum AND potassium
use 1/2 dose weekly to fix this problem, as long as your nutrients have calicum in them you will fix your problem with the fert your using


anyways the food you are using right now what micronutrients does it have on the back and the % o them can you list them or tell me the exact kind of food your using? also what kind of water are you using to water your plant with? RO? tap water? distuiled? bottled? soft water?
also it looks like you have more than one problem here, you look like you got some pest issues, possibly spider mites or thrips
white spots as i see on those leaves are the start of the small infestation that will lead you some problems

look on the undersides of every leaves to see if you can see them little buggers, get a magnifying glass if you have to

also i wish so many people would stop knocking off miracle grow, its not the fertilizer thats doing the wrong doing its the growers mistake!!!! PERIOD!!!!

i used it with bone blood meal but i diluted it with other soil mixture too

i used nothing but miracle grow for my first grow and my plant grew 7 feet tall and i didnt have any problems because i read up on growing first before and knew that NOT LISTENING TO THE BACK of the nutrients you buy in the hardware store or garden shop

using 1/2 the reccommended dose on the back of the box is what you should do and is what i did and i did not have any problems

The nutes I am currently using are 15 - 30 - 15. (Miracle Grow Bloom Booster Flower Food) I've only used them about every 5th watering, watering on average twice a week.
I started them on bottled water, now I am feeding them distilled tap water. Again, I have a Ph Test kit, i just need to find the box to match up the colors.

I know that the choices I've made in regards to water/nutes/soil aren't the best. This is my first grow and i really did it to see what happens. If i ever grow again, I can learn from this grow and do everything the best way. (I'm also a bit tight on $$!) This isn't to say i don't care, I do....it's just that I didnt have the money to go HPS with all the good stuff in the dirt.

if i remember properly there isnt any calicum in your nutrients and very little in the water your using

so feed your plants some tap water as long as its not from a water softner

that should clear the calicum problem up
distiled is kinda like RO but not as clean as RO

distilled water contains trace amounts of calicum and magnsieum which are not enough for plants to live off of if your nutrients does not contain them

which yours does not contain either if i remember correctly

so water with tap water or get some dolomite lime its very cheap and spread on top of the soil take a few tablespoons and sprinkle it on the top soil and put a little fresh soil over the lime and water. get the prelitized kind, you can get it from wal mart graden store or hardware store...... its very cheap like 3 bucks for 5 lbs of it

you will fix ph issues and calicum and feed your plants magniseum all the stuff they are not getting from the food you are using

This just in _ I have thirps. At least i THINK they're thirps. (I found them crawling on the back of the leaves, very tiny almost wormlike) I guess this would explain the white spots.

Also, I had a friend water them for a week, just discovered that he was using tap water from the softener. AHH!!

So i need some more advice...best products to kill thirps & the best nutes to feed that will balance out the damage from the softner.

this is turning into hell.


thanks again guys, don't know what i'd do without you.

 

[sproutco]

Safer soap will kill thrips.

Add gypsum and epsom salts according to the directions above to make the 15-30-15 complete.

Adjust ph of fertilizer plus water after mixing to 5.8 to 6.

Also, I had a friend water them for a week, just discovered that he was using tap water from the softener. AHH!!

thats why your problem got out of control then, water softner will lock out nutrients not to mention soft water does not have calicum or magniseum

i made a thread about soft water......a while back on overgrow

you will need to flush your plant out with clean water. lots of it to get rid of the salt buildup

sodium is so toxic to plants because plants absorb sodium before any other nutrients and plants need very tiny amounts of sodium build up locks out nutrients and causes the plant to pretty much colapse inside..... water up take is poor and same with nutrients and pretty much stunts the plant depending on how well the plant can come back and depending from the amount of damage

the bugs you got are very recently, i cant tell any damage from them in the pics so you are lucky you found them NOW

get some neem oil and spray your plants every 7 days safer soap works good too but i hear neem works better but in this case both would work good you want to get rid of them now before they multiply

sounds like you got spider mites

oatmeal has 10%c and other help full nutes also , very easy to control ph levels my mix 50% oatmeal crushed to poweder from wholegrain unflavored oats 40% organic soil 10% worm castings let sit for 2 weeks mixxed, then mix again 50/50 perlite , never had any unhealthy plants with this mixx alwiss stay green even when danger close to lights

 

[Guest]

well i flushed and neutralised the soil to a ph of between 5.5 and 6. I also used some safer soap on the fan leaves, but i think i am still seeing the occasional thirp.

My hyrdo store didnt have gypsum (they had everything else) so I purchased organic dolomite lime and mixed it into the soil before flushing.

After the soil dries from the flush i will water them with the MG nutes as well as the epsom salts.




as you can see, she isnt doing too great. This was yesterday...today didnt look too much worse, but i think more orange spots are starting to appear on fan leaves in the cola!! (leaves with trichs on them too)

Any advice? This is day 34... and these are the trichs


should i even consider chopping the top early?

thanks a mill guys

 

[sproutco]

Your ph was about right.(5.5 to 6) Adding dolomite lime will cause a ph rise. Gypsum and epsom salts are neutral and don't really affect the ph. Since you added the dolomite lime, you should not have to add the epsom salts now because dolomite contains both calcium and magnesium.

 

[MynameStitch]

yes sprout he wants his ph to raise, thats to low for soil growing
his ph needs to be around 6.5 to 7.0. you should know t hat soil ph does not need to be around 5.5! soiless mixture yes but hes not using a soiless mixture.....


lime will be good for his soil will bring his ph up where it needs to be if he used enough

the problem with your plants looks like ph and or fert burn having the pests didnt do that much damage to the plant....

and thats ok the trich hairs change color bnearly the end of harvest, they die off some of the earlier hairs are the first ones to brown up and die

i dont know why people do by the hairs as to when to harvest, i go by looking at the trichomes
