1/3 from seed 3 weeks old of a particular indica dom I have going has the edges of its leaves curling up. Its about a foot under a 600W MH in coco. I've been keeping the ph at 5.8-5.9 nutes 1000ppm.. the other 2/3 seem a bit droopy. I'm thinking it ph so I'll raise it a couple points and see what happens. Any ideers ?

Raise the lights and lower the temps plus maybe humidity, probably this but could be other things, start here. Peace

Ideers is to post a pic! 3rd week from seed 1000 ppm is on the high side, isn't it?
I'm in rock wool 2nd week of flowering my next feeding I'm thinking about
1000 ppm or should I go higher?

Usually turned up edges on the leaves means heat issues...definately raise the lights, lower the temp...put a thermometer on a stick at the level of your canopy to make sure its below 85F. Use fans to move air around! The 1000ppm does seem a bit strong for 3 weeks in...i'd back off a bit, and your PH is a bit low for a soil grow...get that up to 6.4-6.5 :)

Ph can cause leaves to curl up, and down. And there are no pics to look at.

Imo pH and over ferting may lead to the plant suffering from heat more, whereas your not right your not wrong imo but thats just my 2 cents, everyone says pH without knowing what it really means. Obviously his fert levels might be too high but pics would help. Peace

Problem solved. Could have been the ph which I raised to a steady 5.9 since I'm growing in coco
but it could have also been the fact that I was adding warm tap water to the mix to bring it up to
room temperature. Apparently the hot water tank could be corroding and leaving trace elements
in the water. I bought a bigger resevoir and leave it warm up or a day before watering.
I'll be taking the pics soon.
