Too much nitrogen. Super early sign of nitrogen toxicity. Cut back on nitrogen but maintain upped levels of potassium and phosphorus. Leaves won't repair.

If its too hot try not feeding with every watering. Alternate between water and feed so u don't get a salt build up. I noticed your on a product that is just got P and K and I'm not sure how strong that stuff is regards to rising the Ec. You may have over fed and thats why your leaves are suffering a little.

Nutrient burn?Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅

Overwatering or underwatering or other cause?It's very hot in Rome (30+ degrees) and was away for a week. Got a friend to water mid-way. She gave quite a lot, 700ml. Came back after 3 days, plant was fine. Watered again and after 2 days, leaves dark and wilted. Put in direct sunlight, left for 3 days. Leaves died.

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Wilting and yellowing leaves after vinegar water solutionI sprayed a mixture of 1/4 spirit vinegar + 3/4 water under the leaves to get rid of aphids (which may or may not have been the problem) earlier today. Now checking on her, I see yellowing of several leaves and wilting of others, which has me worried... normal, or a problem? 😳
