Hey, so I started my first grow two weeks ago from seed. Until a few days ago everything was healthy with the leaves praying to the light now I’m having issues with yellow tips on the leaves, some plants have a strange bubble on the leaves and are starting to droop. One plant is more yellow than green, yet I have a few seedling that took longer to sprout are darker green than all the mature plants. Three plants also have what I think could the the claw where the leaves are growing outwards at and angle.
I’m using coco mixed with perlite at a 70/30 ratio, the highest feed they had was 0.8 ec which I have took back down to 0.6 as I was not sure if they were over feeding. It’s been a few days with the lower ec feed. I’ve kept my ph between 5.7/5.9 max. Everything is in 1 litre fabric pots, I’m feeding around100/150 ml per day with about 10% run off as I was worried about overwatering.
I have a small 6’ fan circulating air over the canopy, along with a humidifier to keep my RH around 65/70%. Everything is under a 600w dual spectrum HPS bulb dimmed to 400w running at 24/0 for the moment at around 16’ from canopy, with my extraction on the lowest setting pulling passive air. My average temp at pot level is around 24c I would say the tent is no more than 25c. I plan on changing the light cycle to 18/6 in a few days when the new seeds I popped few days back are more mature.
I’m not sure weather it is a nitrogen deficiency as I have been very light on the coco feed usually around 0.3ec calmag and then around 0.4ec of a&b and 0.1 root stim.
