I'd flush at 6.7, feed immediately with your bloom fert mixed 1/2 strength, foliar feed ONCE ONLY, with a micronutrient supplement that contains a little N, such as GH micro, mixed at 1/4 strength (you have N and micros def too early for a plant that is supposed to go another month), then let the plant get rather dry and pot-up into a larger container if the plant is more than 3 feet tall. If you don't pot up, at least check that the 5 gallon pots have enough drainage in them, and go back to feeding your primary bloom fert at the recommended dosage. Lay off the supplements for now.
Also raise your light to about 2 feet until that leaf curl stops and check that your ventilation is good.
And that IS from a soil pro.

I give up trying to figure this out by myself... are you using soil or hydro? soil what ph is your soil or hydro setup? high atm, 7.2, accidently watered without ph adjusted water, minor flush immediately with ph adjusted water if your using soil what mixture or brand is it? hydrponix soil mix what water temps if you are growing hydro? what are your ppms or EC? what nutes are you using how much and how often? Was using fertilome bloom and root, at half strength, 2 waterings on, one off. what part of the plant is affected? Top Rating: 5
