Yellow tips on sprouts is usually due to more nutrients in the soil then the plan can handle. Too much light can also cause fading and yellowing of new growth. First thing first, check and make sure ph is where it should be. Second, at this stage of growth a 1000 watt light should be about 22 inches away, maybe more depending on power settings. Lastly, make sure you are not overfeeding, and make sure to give plain ph'd water after every 1 or 2 feedings, with runoff everytime. Happy growing.

around what yield per plant might i expect...?I know it's not a consistent number, but does anyone with more grow experience know if there's a good chance I can get over an oz per plant? since they're still not close to being done stretching? this photo is from day 4 of flower, after a decent pruning/defoliation.

Seedling Light-burn or ToxicityHi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?
