Looks like a potassium deficiency their appetite greatly increases when they start stretching in development. This may also effect substrate ph. Could very likely be just going into lock out from ph. First thing I always check.

I'd go with lockout. And what you see is by product of your plant wanting some P. (Not from lack of. Its just flipping and the ratios are wrong.
Water for a few days, and she might unlock herself, if it gets worse, then you'll know she'll be wanting some extra bloom and lower the N. Your Ratios should be 3:1 and before you flip leave it for a few days to unlock.
So 3:1 ratio when you flip will be 1.5 bloom to .5 grow, (once pre flower has started) you can match the micro with bloom, or as you see fit to your plants needs
Good luck pal.

Someone more knowledgeable than me while answer but from what I've been reading its may be an Phosphorous and Potassium deficiency.
My plants are just starting to put a load of energy into flowering so they are sucking the nutrients out of other parts of the plant to sustain the flowering.
Just hit mine with some PK13/14 and a hint of CalMag.

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?
