Clawing leaves, what you reckon? Pics

High

So this is my first grow. I am growing one afghan Kush ryder in an AquaFarm, under a 200 watt CFL and a 90 W Led Ufo. The plant is now 23 days old.

The first week I fed it with a mild dose of fertilizer which burned the two first sets of true leaves pretty bad.
After I changed the water for tap the plant recovered and has been showing plenty of fresh growth for the past two weeks.

A week ago I asked you guys if I should feed it, you told me to wait a week or two. Let it recover from the nute burn.

Since a few days ago new growth has been clawing down and the leaf tips are yellowing. It might be the temperture, since the temps have reached 28 degrees celcius. The PH has been pretty stable at 6-6.5 or so. Humidity is on the low side, the RH is from 30-50.
Perhaps she needs feeding?

My man I didnt read your post. Its to hot up in there. You need to get it cooler. Indicas take heat much better than sativas so when they curl you know its bad. Im guessing those temps are like 87. If the temps are good then its the humidity, very dry conditions will make plants like that. You look like your ballin so buy a humidifier.

your plant will be fine no crazy damage done, but i don't believe its heat stress they would commonly curl up like a hot dog if that happens, i know you are running an aerogarden. in a normal soil grow when i see that, its from over watering. I unfortunately am doing my first hydro grow right now and have limited information. But i would possibly recommend to look up and see if the humidity/water is too much for the plant. keep growing well! looks like its gonna be a beauty

its over fert. Jorge Cervantes says down curl is too high ppm\over fert. flush and go 2\3 or 1\2 strength of what u did to over do it. No real damage done tho no worries.

thanks for your replies.
Probably not over fert though, because im running it on tap. But yeah, does look a bit like that though.
- You guys think its ready for feeding?

lower your ph. 5.5 for hydro.. 6.5 for soil.

I think this is the case, even the pro's get a little nute burn but looks like you could rest your drippers a bit to lessen the drowning look.

Update for future rollituppers dealing with clawed leaves.
Looks like Mystic Clown was right about the humidity. I got a humidifier and lowered the temps, new growth has been looking good.
Thanks for posting guys.
