Overfert?
ostrwahuio
started grow question 5y ago
I'm following the biobizz fertilizers schedule and watering the plant with 1/1,5 l every 4/5 days. Some tips of the leaves are yellow. Do I need to worry? How should I handle the situation?

Overfertilization, you have to give nutrient one times and water 3 in soil before giving again nutrient.

Brown spots on leaves
What seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue? Is there a fix to this? I grow in soil and the plant is 4-5 weeks old. Thanks for help!

Give them food or not ?
hello it is time to water for some, they took 15-20 days to drink their water. I fed them at the last watering but I hesitate to feed them again because of their light color? Thanks

Нлвые проблемы с переводом на цветение
Заметил побеление на кончиках листьев. В основном на нижних, но есть и на паре верхних. Не могу определить, то ли перекормил, добавив Bloom booster, то ли дефицит калия и кальция с переводом на цветение, буду рад любым советам и адекватной критике

Hydro. If the plant is overfed, can the ec possibly go down when they are given new nutes ?
Usually they eat 0.1 ec when I add nute or with a new tank and ph goes up. Then it stabilizes and ph starts to go down till I refeed since I have a small tank. Right now there maybe a nute block but EC still goes down like they are hungry... Hydro with a small tank is confusing..

KronicAquaponic
Lime green and droopy
So she has been getting lighter the last couple weeks since the soil became too wet from being too deep in the aquaponic water, figure it’s ph related but I flushed her twice, each time ph came down, but didn’t seem to help, am I going the right direction or is it just N def now?

Magnesium - Nutrient problem
Do I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly. The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1. Has anyone the same problem? Thanks!

Is it a copper deficiency? I use RO(no deionization) since the start, I'm at week 8. the last watering, I used tap water that was under the sun for 16 hours for that reason, since I can't see until a bit if it does something I was wondering... Thank you

Heat, RH or overwatering? Or alltogether?
Hey my fellow growers! The grow reached 32Celsius the last 2 days in the last hour before going into night time. On that time RH goes down to 32% and this seems like it's stressing this lady a bit. Yesterday fed her nuts - maybe a bit too much? Thank you for stopping by!

Outside Transplant Nutrition
I am going to be transplanting to an outside location. What is the opinion on needing to fertilise the soil before the transplant? I’m under the impression that if the area is littered with brambles then the soil is already ideal?

Lockout? Can I remedy this late in the game?
I think this is more than a K deficiency. I think I'm getting lockout. And a lot of it. She's an auto-flower, and I grow hydroponically. Can I even remedy it at this point?
