Warum werden die Blätter auf einmal so schnell gelb und welk?Hey, meine Hawaiian Runtz ist Ende 4. blütewoche. Gießen tue ich alle 4-5 Tage mit 2-2,5 Liter Wasser und 6,5 ph Wert, immer ziemlich identisch mit Terra aquatics ph Tropfen, also sollten ph Fehler ausgeschlossen sein. Temps am Tag ~28 und nachts 26 grad Celsius. What’s wrong?

Leaves downHello,fellow growers. My Royal cheese 🧀 seems to be doing not so well in her second week. Leaves are turning yellow and down. Can this be because of overwatering ? I gave her two litters of water two days earlier and now it's all sad. Please help me out.

Leaves of plant are clawing but not sure on the reason why. Suspected nitrogen toxicity as nutrients have 2.1% nitrogen and was feeding everyday. Have laid off.. and will be doing twice a week. Is this right? It is the only thing I can think of that is causing clawing..Week 1

The plants colors look healthy and about 8 flowering sites appearing on NL and 3 on WW. However, the leaves, particularly on the NL look to curl under. I've been having little trouble keeping the pH in the 5.5 - 6.5 range, seems to drop to the mid 4s daily, but fix quickly.Week 4
