Yellowing of the lower leaves during flowering is quite normal/common, but either add or up your P/K booster to help your plant, she will be hungry for phosphorous (P) and especially potassium (K) during flowering.

The damaged leaves won't recover, but it will prevent the other leaves from suffering the same fate.

Leaves keep turning brown and yellowIt all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it.
My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead.
What do you recon, why could it keep getting worse?Leaves. Color - Yellow

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. Curl down

If this was yours, how would you proceed?Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?6y ago
