Are you giving any nutrients yet? Coco coir doesn't contain nutrients so you need to start sooner than if you were growing in soil.

Slight Yellowing on tips of new-growth? (VEG)Why am I getting slight yellowing on the ends of new-growth leaves? It's affecting every plant. The only clue I have is that it might(?) be related to very cold nights because of my re-vegged photoperiod showing purpling on the edges of its leaves. Any ideas?

Brown spots, PH in run-off is in the high end (6.5~)I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?

Harvesting a struggling plant or just letting it fight Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Leaves turning yellow with brown patches I noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

Yellow leaves (a lot of them)The plant is showing a lot of yellow leaves. I think it's a little bit early to speak about a natural loss by flowering, or not? There are also a lot of yellowish leaves (more yellow than green even): what is the problem? the red leaves are normal to this strain I think? Thanks!

Yesterday i see new yellow leaves (plant 2). I have just checked them again and on the second plant the two small leaves are now brownish. What could that be? I water every two days and the soil is not wet but slightly moist. The other plant 1 grows wonderfully.

Is this a CalMag deficiency?It started with White Widow a few days ago, showing signs of yellow leaf tips. I'm quite sure I'm not overwatering. Are they overfed (nutrient burn)? I use plain water and applied Zamnesia Monster Bud Mix (Pellets) to the soil before the grow. Scared for my first harvest.

Lowest leaves turned yellow After a very hot and sunny day (about 37°C) I noticed that the lowest leaves turned yellow. Is this a sign that I should use more Terra Bloom? If so, how much more should I use?

Outdoor northern lights auto yellowing early With 3-4 weeks of flowering still to go, how worried should I be about rapid yellowing? I have kept feeding, i know she is rootbound and I havent checked pH. Do some plants just yellow earlier in flowering or should I act?
