Hey guys, I'm pretty much a noob and have some newly transplanted clones showing some issues. I transplanted them 3 days ago into a coco hydro system. Watering once per day with RO water and using GH Cocotek at 75% of the feedchart 330ppm (ebb/flow system - 15 minutes between flood and drain). I am not currently using any CalMag because GH told me from an FB message that none should be necessary. And now going into today I am seeing this. I am also running about 1000 watts of LED 24 inches above @18/6.
PH has been around 5.8
ppm: 300ish
water temp: 78
tent temp: 85
humidity has been as low as 25% but usually around 40%
cocotek grow a&b at 75%
rapidstart @ 1ml per gallon.
Is this mag deficiency, nute burn, over watering? it happened so quick.
I'm no expert by any means, but my guess would be too much nutes/maybe transplant shock. The yellowing insides of the upper leaves there, the burnt tips, and what looks like maybe a phos deficiency on the lower leaf there in 2nd pic make me think it's just got too much for a young plant and is locking out some things.
But also again, I'm new too.. and not familar with GH nutes or your grow method (i just use soil).
