Curling Leaves?

TeeAychCeestarted grow question 4y ago

Anyone know why these leaves are curling? I’m currently low stress training by bending the nodes and stretching them apart with garden wire, is this perhaps why? Second plant is a week behind, no LST for an experiment, all replies welcome, many thanks 🙏🏼

Nitrogen toxicity from feeding too much or too often, or both. Remember, in soil it is plain water/plain water/feed/plain water/plain water/feed...... If you are growing autos, half strength nutrients is usually plenty strong enough.

You're giving them far too much nitrogen... I'd suggest you flush and then back off on your grow nutes by half. Make sure, too, that you're getting the PH of whatever you give her (water or nutes) between 6.0 and 6.5 so you don't get a lockout and face deficiency issues.... Good luck!

Bent and twisted leaves with brown marks in 3rd week of veg. What's wrong here? (I wrongfully tried to feed them nutes in the first week of veg)Hi Guys. 2 of 5 seedlings sharing the same reservoirs with water seem to have some issues because the leave tips bend downwards and they have some brownish marks on some leaves. These are 2 different strains, a fem and an auto. Got PH 5.7 and fresh water for 2 days now.

Crumpled new growth?I've noticed that there are new leaves towards the base of the plant that are growing strangely. Could this be from low humidity? I've been having a hard time keeping it up. I also noticed that some of the leaves are clawing down (see week pics). Perhaps related? Haven't fed yet!

Have popped 2 seeds, 1st week of grow. One plant started to roll down her leaves extremely right after losing the shell. Anyone knows why? What to do? Had extreme dry RH in first days, it dropped down to 36% sometimes. Both plants have root fungus in substrate. Thanks!

Overfeeding or Overwatering?Growing in coco and watering with 550 ppm 6.1-6.3 everyday. Does this look like it needs less nutes maybe or less water? Today’s run off was 625ppm so I gave it just ph water. Was also thinking wind burn?
