Leaves - yellow tips and wilting.

Not too bad, but mid photo shows signs of nitrogen or potassium deficiency.

It doesn't look that bad, when was the penultimate watering and the last one aka how many days were there between watering? Too many or too less + too much water and they will have a droopy look. Tip burns have a wide range of reasons, e.g. air temp little too high, overnutrition, cal/mag deficency. Usually i let them drink out, rewater them with half the nutes and see how it goes from there.

I assume it's a root problem. Have you checked the temperature in the pot? My plants showed the same symptoms before I found the source of the problem. Below 18 degrees the root zone goes into shock which causes metabolism to stop and nutrient uptake to stop completely.

When Your plants Turn dark Green then they have too much nitrogen. The plant needs huge amount of Energy (ATP) to reduce nitrates and aminos. For Nitrate they have to reduce for 8 stages. That means the plant has less Energy to Work with the other nutrients. Without enough potassium that can be used, the Stigma cant Open and Close properly and the plant cannot breath properly. Then Theres for exemple Heat Stress etc Many calmag Supplements have nitrogen which is Not good after the Stretching Phase of Your plant. Is recommand to use PK fertilizer with about 1N 2p 9k or sth Like that and when Your plant IS showing that shes Not doing great Always reduce the light in First Hand.

Nitrogen toxicity and a magnesium deficiency at the same time. How often are you fertilizing? In soil, a schedule of plain water/plain water/fertilizer works well in my experience. Certainly do not feed every time you irrigate! Remember too, it is very, very easy to fix a slightly under fed plant, but very, very difficult to rescue a burned and damaged over fed plant.

Sounds like they are a little wet. Let them dry back before watering again and see if that helps. Get to know the weight of your pots. If you can pick it up and it is heavy don’t water it if it is light give them a drink. It’s how most of us learn.

I think is overfeeding and overwatering. All mix soil could be hot for some strains especially sativa. Good luck!!

A dal? jak casto a cim hnojis ? kolik tam toho davas ? nic si tu poradne nenapsal zadny informace a chces poradit ???'!!!! jaky substance ???

Hey, i checked you dairy. You fed her only a organic grow fertilizer used for vegetativ state. If cannabis is fed only with an organic 5-3-3 fertilizer through flowering, leaf symptoms usually show a nitrogen excess and a phosphorus/potassium deficiency. Leaves stay very dark green, often thick and heavy, with slightly clawed tips. During early to mid flower, lower and mid leaves may lose vitality, show dull coloration, weak turgor, and later develop edge burn or necrotic spots from potassium deficiency.
