looks like mag to me, maybe a lock out?

 

[pizzadude]

also to add, i would assume it's too late to foliar feed(these plants still have 2-4 weeks to go easily and bulk up), but i recently bought some epsom salts so they are on hand. Only other products i have here are

floralicious bloom and plus
superthrive
Pure Blend Pro Bloom
Hygrozyme
Molasses
and not too much time

could be, i was told to raise my ph up to 6.6 area from 6.2. I don't think i can go higher though safely at this point but not sure. Still new to dirt. thanks for chiming in Duder!

Excess phosphorus

 

[pizzadude]

to correct?

 

[Blackvelvet]

Pbp bloom for soil has a ton of phosphorus. Then you added more.

How long ago since you repotted into moonshine mix? How much dolomite lime per gallon of mix did you add? How much pom ferts were added and what were the npk numbers? Ex: 10-10-10

 

[pizzadude]

been in MSM since day one, repotted to 1gallon grow bags 3 weeks b4 12.12, so 8.5 weeks.

very little POM in each container, it was like 1 cup to 3 bags of soilmix. only fed 2 times with PBP

You might be right about needing more magnesium. Over two months without fresh dolomite lime and being watered could have washed alot out. Try drenching the plants once with 1 teaspoon epsom salts per gallon of water. Will not hurt the plants even if your wrong.

Thanks BV! I appreciate you takin' the time to help me out. I just got back and flushed the pots with about 4 to 1 ration of water to soil of fresh water, gonna give'em a day or two to dry out then hit'em with epsoms.

unless u think it's ok to just drench them sooner right after the flush? i figured i should give them at least 24hrs to dry/rest, they got a thorough flush

 

[Blackvelvet]

Wet is wet. Go ahead and drench.

You can feed pbp with every watering. Try about 20 ml per gallon (1 teaspoon=5ml) Don't add extra phosphorus. It has plenty. Ph adjust the fert water before applying for best results. Make sure you get alot of runoff each time you apply.

i just gave the worst ones a nice drench with epsoms(1teas p/g) are a few others that were showing similar signs a lil cup full, time will tell now.....
