Mongodudu is right, your girls is needing some cal/mg but dont just add on top of your other nutes. Reduce the other nutes ppm by the amount ppm of cal/mg your gonna give. Cheers

Magnesium mate. Calmag should help her out, if the pH levels are correct 👍🌱

N starts with light interiors and dark edges and before making two floors there is already at least one yellow leaf usually, so that's not your case in my opinion, and man if your calmag is 8-0-0 is shit in my opinion you can't use it in flowering

I'd say Nitro, But i'd also use my CalMag, because it's NPK 8-0-0. May you have a look at yours. Good luck🤞 Servus OimRausch

No N, go with calmag to enrich the soil with cal mag and micronutrient

Too much nitrogen?What does that mean? Maybe too much nitrogen or too much nut at all? If it's too much nutrient you think is better feed once with nutes once with ph water or every time fed with nutes but one time half of the dosage?? Idk please let me know

Lower leaves turning yellow and getting crispy Lower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.

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.😅
