Please help! My white widows need an expert!

[stnr4life]

Im a newbie at this, this is my second grow.
400 watt hps and a 250 MH for vegging and two 400 watt hps for flower. Problem that i cant solve is that in late vegging my plants begin to turn yellow starting at the lower fan leaves and curl up. They drop off as quick as i can pick them up.

I've been using earth juice grow which is 2-1-1 for the first batch and for the last i have been cycling earth juice grow and alaska fish emulsion which is 5-1-1 every other week for vegging, and alaska morbloom 0-10-10 for flowering.

I water everyday as the soil feels dry and fertilize once a week- Im using fox farm planting mix and in two plants i also added perilite.
What is going on? Am i doing wrong? Why yellowing leaves? They are all falling off again on 3 different plants?
Could they be root bound?
My plants are 2 1/2 to 3 feet tall in 3 gallon pots?
I tried flushing with no effect?
PH is 7.2
they are always perfectly healthy til bout 2 feet tall in vegging. I have other pretties started and i dont wanna fail with them too

Sad stnr

I am no expert but i will try and help. Where are you getting your PH levels from? (ex. soil, water before feeding, or drainage water?) I am thinking you may have some nute lock issues. Does this happen to all your plants or just 1?

try lowering the ph to 6.5 or lower, might have a nute lock I loved my WhiteWidow!!

They look N hungry, fix that PH first.

 

[snuggles]

I concur with both of the above posters. Other than that they look nice, so do the plants in the background...good luck.

I took the ph reading from the soil about four days after my last fert. This is my second batch ever and as with the first, all plants in late veggin begin turning yellow. I will adjust the ph.

Any ideas on how to bring down the ph without fancy additives? Ive heard crushing egg shells and soaking in water will help equil that out.

 

[bigbudsbruddah]

I seen this in the Ready,Set,Grow videos

Baking soda to lower ph

Vinegar to make it go higher

 

[smokybear]

Dolomite lime is pretty cheap and will lower the ph. Just put some on the soil and water in. They look like they need some N. Keep us posted. Take care and be safe.

 

[trillions of atoms]

^ yup! they need more N!.... ph needs to be 6.5.

 

[stnr4life]

Thanks alot guys n ill keep ya posted here. I may just stop and buy some ph- down solution.

It shouldnt be a prob that im using one of those cheap $20 analog testers should it? I mean - to be accurate i dont need a $180 digital tester do i?

 

[stnr4life]

Hey folks... so i got some testing supplies and i find that my ph was up a bit to 7.2. I added some ph down to correct the problem.

I dont think it was nute lockout as for my test kit showed it had a surplus of p and k and very diffecient of nitrogen. I thinks its just a nitrogen diffiecency. Added a boost of N and they are turing greener.

Hmmm guess i forgot the fact that as they grow bigger and get huge they demand much more nitrogen. ive been givin them the same dose since birth!

SOunds like things are on the mend, but I'd also put them in bigger pots before you put them into flower. I always use 5-10 gal for my white widows.

You also shouldn't be watering every day. Your roots need to dry out in between waterings to effectively absorb the nutes in the soil.
