Hi Guys, ist this a sign of too much or too less nutrition? Or is it something else (too much light/wind)? It started a week ago and i thought too much nutrition. So i gave a few times just CalMag and Bloom w 0.7EC. Didn't help... She is 2-3w away from harvest, Should I worry?

Damaged leaves will stay damaged and any changes you make will take 2 weeks or so before showing any signs in the leaves. Yes, over fed. In soil, feeding only once a week to every 10 days is ample. It is not light/wind burn or "the fade". I think you still have 3, maybe even 4 weeks to go according to this picture of this plant. Once there are 98-99% brown pistils, you will be entering the harvest zone.

Too early for fade. I saw it only on one plant, others looks very ok. Think its potassium, just toxicity of it. Not a biggie if not progressing.

Too high ppm/EC. Dial it back a bit. Get more perlite in your grow mix next time. It will help with aeration and allow you to uptake nutrients better. Best of luck on your grow.

You could check your Soil-pH and DLI, from the pattern it could be llight. I dont see a problem in your feeding if your diary is accurate. Just my opinion, but I wouldnt cut nutrients completly just lower the dosage, you have to see them as a living organism. They get used to dosages, ph, light, everything. With organic nutrients it may work, but with mineral nutrients that work instantly i doubt its any good to go from 100 to 0.

Is it warm enough.It wants to be over 27?If its not warm enough this could cause bleaching of the leaves due to the leaf surface temp not being high enough,if you're using led,s that is.The more info you give the easier it is to work out.

Its either light strees or lack of nutrition.
