Feed daily & aim for a minimum of 10% run off....

at times, like in veg, i can sometimes not feed for 2 days. what i have to do is set the ph to 5.5. over the 2 days it will rise up to around 6.2-6.3. giving it full access to the range of nutes.
when they drink enough to feed daily, it also means the ph rises faster too, so once is a minimum.

if your feeding twice per day the ph can be set to around 5.8. by feeding twice per day, it wont drift as much. it will go from 5.8 to 6.1. well within. a good ph range for coco.
and with 20% runoff everytime, your are essentially flushing your plants of salts in the medium.

your ec level seems fine at this stage. if not a deficiency, then maybe genetics.

is it coming through on new growth or just the big leafs?

can you dim you ballast to 400w for now?

Thanks for the reply’s, I been feeding every other day to entice root growth and usually up feed to daily in flower, I will feed daily from today I always allow for a little run off

I will also check my PH again

I can’t dim the lights sorry but the temps seem fine with the 600w
