A few leaves look like this. What is your opinion? Week 3 flower.

Only one plant of four in my main flower room has this issue. It's a white queen plant. Only a few leaves near the top have this.

FFOF-Perlite-Worm Castings-Dolomite Lime

1/2 strength doses of full Fox Farm nute line-up every other watering. Fabric pots. Epsom every 4-5 waterings. Calmag every other. Humic acid at low levels every third watering. Just started molasses last watering. No other plants have issues all are full or dominate indica.

6.5 pH soil. Sorry for HPS light pictures.

how are the temps? and what colour is the discolouring? is it more of a purple or brownish? hard to tell with the lights on. the leaf twisting can mean fluctuating ph levels. is 6.5 the water going in or is that you're runoff?

Temps are 77-81 day-----65-67 night. 50% RH

It's a rust color, brownish, no purple. Yes, pics under HPS suck.

6.5 is runoff. I usually master my pH around 6.5 by end of veg. The fluctuations from week 1 veg to current are only between 6.2-7. Looking back in my journal the white queen was tougher to get to 6.5, she sat at 6.3 late veg to about a week ago. Currently 6.4-6.5.

well it sounds like you're treating her right man, she might just be a bit of a touchy bitch. it doesn't look like its a to big of an issue, at the moment anyway. I'd just keep doing what you're doing, maybe try get the ph just a tad over 6.5 and keep an eye on how it progresses

Exactly my plan, up the pH a bit. I'm feeding her everything she needs and never go overboard so no real deficiencies should be happening. Being she is the lone one acting like this and I know feeding more of something when you have an unknown issue is worse then just observing a little longer I will just bump up the pH and observe.
