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.

Help with gnats
Help with gnats. I’m frustrated. I’ve tried everything. Even repotted and flooded soil with peroxide mixture. Neem oil, Severn powder, traps. Plants aren’t declining anymore but still some new leaves yellowing.

Yellow tips
New grow, new leaf colours! I think it could be over feeding, but would like to see peeps opinions if possible. Have stuck to the feeding schedule, but the fabric pots might be making things more complicated somehow?

Leaf tips yellowing. Overwatering? Or nute burn?
I recently flushed my soil with water that was PH 7 (my soil was a bit too acidic). My question is: are the yellow tips and browning due to the overwatering from the flush? As well as stripping the soil of its calcium? Thinking of giving them 3-4 days before watering with calmag

New growth and top leaves have some discoloration. Could it be light related, or maybe a zinc deficiency?
She has been flowering for about a week now and showing some pale spots. At the start of flower I turned the light up from 200w to 300w. Light is currently at about 20" from the canopy. Plants seem healthy otherwise, should I be concerned?

I'm already seeing yellowing and on the largest plant, #3. Is that due to growth or am I over watering? Approximately 2 gallons in the wick bucket every few days when it starts to feel dry, but I generally spray the top with water on a daily basis, not more than a 1/4 - 1/2 cup.

Underwatering Issue or something else?
I haven’t been tracking exactly how much I’ve been watering. I usually water until run off. I’ve had to water daily because the coco loco has been drying out quickly. Is the yellowing seen in photos from 4/28 due to underwatering? I’ve been pHing between 6.2-6.4

yellow/dark discolouring of leaves late into flower
Noticed this on about 5 leaves, some more affected than others. The plant is towards the end of the flowering, with about 3 weeks left, better to ignore it now or try to do something ? perhaps leaf Septoria, already increased air flow and decreased humidity

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?
