Cream auto from Growers Choice. Week 9 from seed, 5 weeks into flower. The issue you see was only on a few top leaves but now is getting widespread. My first ever grow had no such issues till now. Only thing I can think of is I switched from spring water to tap. See more....

Я не знаю на чём ты растишь....если это просто коко, тогда не надо Flush! просто меняй раствор, ставь ph5,8 как для гидропоники на цветении! 👌 И проливай его со стоком, замерь ppm залива раствора и дренажа! сравни, выяснишь, ест она или подавилась... водичку однозначно кислую надо, она любит кисленькую пить ✊😇

Бро, ты не один сегодня с таким делом пришел! У тебя проблемы уже давно, не ты только сейчас обратился, когда пошел такой АД! Передозировка азотом, уже стадия перенасыщения, ткани пытаются отмирать, вижу что листва внизу глянцевая и очень зелёная! Эта проблема у тебя уже давно, друг! Вначале твоё растение было очень зеленым и красивым, но всё пошло иначе с цветением! Ножка листвы красная - недостаток фосфора, он заблокирован передозировкой азотом! Это беда! Это одно на другое! тут нужен flush по-технике и обязательно добавить свежей почвы наверх, если flush будет сильным! 👆 Проверь свой сток ppm при проливе! Снизь добавку Gro в 4 раза! Увеличь добавку Bloom в 3 раза! Соотношение 1:4 Gro:Bloom! Давай 50% дозы удобрений от рекомендуемых их производителем!!! ✊😇 Удачи, друг! Надеюсь ты её спасешь... но она тяжелая 👆

Hey! This looks she might have a calcium deficiency, are you using Calmag? Could also be root problems or PH fluctuations.. After switching to tap water, are you still controlling the PH when feeding? Good luck and Happy Growing!😃🌱🌿🌲

Too me this is not ph.. I'll tell you why every time I see excess ph problems in my hydroponic set ups it almost always has drooping foliage... I don't see this here... Which tells me your balance is off with your nutrients. I think your tap water has a lot of Calcium in it that's your problem... I don't ph my soil grows.. My grow friends do not ph their soil grows... Ph soil grows is a really weird thing to do and might only be really required if you have ph out of 7 range.. My ph is 7 it goes into Acidic soil the soil and the water make for a balanced ph. PH is really important in hydroponics.. Plants in soil have been self-regulating there own ph for thousands of years..

No diary so just guessing Tap water is fine but you MUST check PH no matter the source of water. Sooner or later you get this if its not done. Have to keep the pens calibrated also , found that out the hard way. No getting around it Calcium is locked out which says PH was below its range as I dont think there is a practical limit on it on the alkaline side.

Sounds like you nailed your own problem. Add that cal mag back in and either go back to the bottled or get some pH down for the tap. ✌️

Always used bottled spring water never checked pH. Never an issue. Recently switched to tap water that I let sit overnight but again never checked ph. Seems my tap water is a bit alkaline around 7 or perhaps even higher. So I went back to spring water today, pH around 6 and flushed the heck out of her with a few gallons pure water. I wonder if high pH from tap water locked out minerals and I have a cal mag deficiency? I feed with Neptune’s harvest fish emulsion (0.5 tsp per gallon) and lately added canna terra Flores 15mL per gallon. I stopped cal mag when I switched to tap water two weeks ago, which could also be an issue. When I used cal mag (GH calimagic) I used 0.5 tsp per gallon. She’s in FFOF in a 3 gal fabric pot. Thanks in advance for any help
