PBP?

[sour d tox]

I am using the pbp soil during flowering (2 weeks in )with cal mag and super thrive. ph around 6 and the leaves are turing yellow and starting to look like burn on the ends, when do you use the nutes? every watering or everyother? what should i do, does this sound like nute burn or a def.? i just put have bloom and half veg formula because my freind suggested that it was nitro def.

Burnt leaftips are a sign a overferting,I would drop the superthrive especially during flower.I use PBP veg as directed every watering,never tried the bloom formula though.I plan to when my tiger bloom runs out,I'm impressed with PBP soil.

16.67 ml pbp bloom for soil + 5.8 ml cal mag plus per gallon of water. Apply with every watering making sure to get alot of runoff. Ph adjust the fert water before applying.

If you recently repottted and used dolomite lime, you don't need to add cal mag plus. You would then up your pbp bloom soil to 20 ml per gallon. Can't really use more because it has so much phosphorus and can build up in the soil and become a problem especially preventing zinc uptake and function in the plant.

yes i limed half of them while in veg and the other half when i put them into flower 2 weeks ago, but i also added mag to it is this a prob? also super thrive is not a good idea? how about hygrozyme & hygroguard i have both but havent used them in flowering yet. when will i need to add cal-mag back into the mix or will the lime be good for the whole cycle?

Are you using R/O or tapwater?I use calmag plus every other time 5.00 lol ml. per gal. with R/O water.Hard water is highly calcified already

 

[sour d tox]

i use tap water , but the water in my area is on of the best in the country around 7.0 ph and 0.24 tds.

Im having a similiar issue.....I have 2 gardens with completely different water sources.1 is consistently nicer then the other. The water in the nicer one is spring water the other is well water.I live in an area well known for good water.
I have a ppm meter,but is this sufficient for testing tds?My ppm of my fresh water doesnt even register on my meter.But my meter only goes down to 200 ppm.....so I could still be having a water issue?My fresh water ph is around 6.7 which seems perfect so the only thing left is the tds. Right?
Too make matters more confusing the nicer garden has better soil,but I dont think thats the problem.....even plants in fox farm didnt seem to do quite as good in the well water garden.Took them long time to start really growing quickly compared to the spring water garden.
Got any ideas?

lime?

lime?

Maybe I should try adding dolimite lime to some of the plants that are growing slower and look paler then the others?And see if this remedys the situation?

 

[Dj Zion-i]

Btw sour d for your problem Id water that plant(s) with plain water till it runs out the bottom a couple times.Then I would saturate the soil with a 1/2 dose of 16-16-16
Maxsea fertilizer made by botanica(not botanicare)..and wait 4-7 days to see the difference.Plant should turn a nice dark green,and have noticably nicer new growth.

16-16-16? and the fertilizer can be used with the other mixes?

here are the picture's of the leaves?

That appears to be a nute burn IMO, also look at the FAQ's on this matter. You should start with about 1/3 of the recommended dose to start, then gradually work up to the recommendations.
Also tryin, try to do a flush of the soil, it will give the plant a chance to start over of sorts,
If it takes 1 gal of water to get some run off, then you should use at least 2 gal to do a flush.
Then go to the 1/3 formula.
Thats just my humble opinion. Chi ne he

plants are being watered with pbp@15ml a gal with 5ml of cal mag,is this to much?thought it was hard to burn them with pbp? have 6 plants-same strain in a hydro setup with gh 3-part nutes running full strength(still in veg) and no problems,just dont get it

 

[Guest]

You're in a hydro setup?What are the condition of your roots?Why are you bothering knucklehead dirtgrowers with hydroponic anamolies lol?

have plants in soil and hydro
roots in the hydro setup are growing like crazy,nice and white,not all the plants in soil are having problems,just trying to nip it in the butt before it becomes a problem

flush those babies

only use the maxsea in conjunction with other fertilizers after you have built your plants up to regular feedings.
its 90 percent organic(10% aprox. amon. phosph/nitro)
you for sure u have a fertilizer burn.Dont stress could be worse..just flush em good,like i said,and water with a half strength hi nitrogen ferty if u cant get the maxsea.Within a week your plant should trun a nice lush dark green and start growing rapidly.If it doesnt you most likely have a ph problem.
The maxsea should help alot the kelp in it stabilizes ph,and catalyzes locked out salts into available nutes.The stuffs magick.I sometimes hit sick/yellow plants with a real strong dose of it and they go into a major rapid grow,and have no problmes for the rest of the year ..LOL.My favorite fertilizer for outdoor forsure and works on indoor good too.But im still of course searching for a better one for indoor.Im gonna try using canna ferty with canna coco.Right now im trying ocean forest with the complete line of foxfarm soil nutes(Cha ching, open sesame,big bloom,tiger bloom,etc.)

 

[sour d tox]

thanks everyone i will try to flush them and start over with less nutes and give them a week and see what happens. i had a feeling it may have been burn but i heard that the PBP had a bigger buffer toward burning then non organic.

 

[Guest]

If anything is burning your plants its that superthrive crap not PBP,I dont know about the bloom formula but I can't even get a yellowing leaftip using PBP grow full strengh every watering on larger vegging plants

 

[tryingtolearn]

I still dont know whats going on with these plants? The one's in veg are doing great,nice and green-seems like when they go into flower is where the trouble begins
veg

flower

could it be they dont like the extra P in the flower nutes?

 

[Guest]

Either thats a mag defeciency or the light is hitiing those fans in a way to make it look just like a mag defeciency
