I thought I have been keeping my p.p.m.s low on my nuets, but is it burn from too much food or am I too close to my light? Any help will be appreciated!

Calcium and phosphorus for sure. Too many light for these babys so they need more phosphorus. Solution is to raise the light higher and spray Calcium if there is enough phosphorus in the fertilizer.

and its to hot.

calcium..100%

forgot to lst super crop and tie down eh
orrrrr is it your first day on the job:)

looks like some fan burn

im assuming that could easily be PH fluctuation, but it could also be nute burns; first indication of nute burns would be yellowing tips on majority of the fan leaves. and as for the light, LED doesnt give off much heat, you could actually leave your plant no closer then 12inches away with no problem; i was growing with 180w LED and left my plants approximately 12in away and grew beautifully.

pH problem

Looks damn healthy to me and too many nutes would curl the leafs twisting them and would be quite obvious! Lightburn would be at the highest point an burned brown. Just stay consistent and watch the plant how it reacts. Start with lower nutrients if she's not growing everyday and work your way up watching very closely for changes. Air temperature and pH are soo key along with aerated roots if using soil. Hydro is a whole different situation but everything can be controlled just takes more time and$$

I just added too many nutes to my plants in an aerogrow system. What do I do! I changed out all the water that I could, but the leaves are still drooping. It literally just happened, but am I already too late? Will they grow back or recover?

Why is your plant a sphere?

jay anchor might have it too,didn't think of PH.

by cycle I mean how much of what nuets and how often you apply them,but for what your using looks like you're on point ,if you have any doubt cut back ratios a little for a few feedings to see if it clears up,some strains are more sensitive, but I think you got small case of light burn,raise them up& you'll be good.

don't know your nuet. cycle,but from here I'd say light burn.keep it growing!

There's no way it's light burn since your lights don't run hot. It might be because of your nutrients or your water ph isn't right. Growing in a small pot is always hard on the plant too. Also don't worry about a leaf or 2, you can't have every leaf perfect. Worry when it's your whole plant
