Ph is always 5.8 - 6.0 RH is always 50% - 60% Light is 400w hps Res temp between 77 - 82 Room temp between 75 - 80 Her leaves started yellowing at day 7. At day 8 I moved the 400w light down to 12" from her. By day 11 she had damage to the tips. At day 13 I moved the light 3' above her and the damage continued to worsen. At day 14, I moved her to intensive care under a 40w flo and her condition has leveled off. It can't really be nute burn because I only added 1/2 tsp of grow and 1/2 tsp of micro to about 7 gals of water at day 8. The attached photo is today at day 15. I looked at photos of heat stress and they don't look like her. I thought it might be nute deficiency too. I wonder if anyone can tell me what they think caused this? Thanks. Crack | ||

hey man, yeh i doubt its heat stress and i doubt its nute burn, i do think it could be light burn, my plants got a bit more then yours and a 400w hps is fairly powerful for a lil sprout, if its only 11 days old i wouldnt even be using nutes mine is 14 days and i havnt thought bout usin any yet but all to their own i guess, if its not light burn i duno wat it could be but that does look mostly like light burn, tho im not a pro so wait for more opinions first peace

| Good Advice man! Way too much light for your little ones. Raise your lights as high as they can go. Maybe even put a shade cloth to reduce light. Keep nutes at lowest levels for a while until they start grow rapidly. Anybody else chime in if you have any other advice! Later

 | I'd say heat stress from being at 12"...or maybe even over transpiration....any 400 watter is alittle too intense for seedlings...even after its foliage it should be acclimated to the higher hid's'......another thing...hold back alittle on the micros until youre at full nutes...hyperaccumulation of metals can do that too....I 'd start over...dump what youve been using...Good Luck  | ||
