Hey guys. I'm on my first grow here, growing in coco with 30% perlite, and 3 of 4 seedlings are drooping (only the first set of leaves though) on day 9 from sprouting. The last one looks great and is about an inch taller than the others with bigger leaves also. The drooping appeared over the last couple of days.
I've been watering every one to two days, alternating between nuted and plain water, when the top of the coco has some dry spots. I've been thinking it might be overwatering causing it, but why would one of the seedlings be fine? Also, I've read so many guides and posts claiming it's very hard to overwater coco and you should water every day, and others claiming you should water like soil. So much conflicting information, hard to make sense of it.
If it is overwatering shouldn't the second set of leaves droop as well?
Details about the grow:
Light: 400w MH, about 2' above top of seedlings, 18/6 cycle.
Humidity: around 40%, hard to get higher because of extractor fan.
Temps: about 80F at top of seedlings, got a small fan blowing over the plants.
Nutrients: GH Flora Micro and Bloom at a very small dose for the first week, + a ts of CalMag per gallon.
PH: water is PH'ed to about 5.9 before mixing nutrients. Haven't really measured runoff.
Strain: AK47 bagseed.
Pictures are of the and a drooping plant and of the good plant, with drooping plants in the background,
