Hello fellow growers, Does this look like nitrogen toxicity or clawing? There's also some nute burn from allowing the reservoir level to drop too low. Setup is flood and drain hydro using Jacks 12-4-16 with epsom salt at 1400-1800 ppm. These plants have 10-20 days left.

I give them a light feeding. Between 100-300 PPM(500). I don't control the humidity but I do control the temp with an extraction fan. The light is on 24 HR per day. The blocks are kept damp but not saturated. I'm honestly not sure why they have flowers. The mother that they come from has...

The clones aren’t from a flowering plant…. They root quickly. 6 or 7 days. They just look bad. I’m giving them no veg time before flowering so the healthier the clones the better the final plant. I’ll try raising the humidity.

I've got a cloning problem. My clones always root but they slowly lose leaves. I need healthy clones for my SOG op and they need improvement. Clonebox Conditions Temp= 80F Heatmat set to 80F Light is 19W LED RH= 65% Any ideas?

I've checked for light leaks and found none. The rooted clones I flowered had taken a beating in the clone box. They had some dying yellow leaves that I removed. They also barely grew in height in the 3 weeks in the flowering tent. Could that stress have caused them to turn hermie?

I think I already know the answer. I just want confirmation. First grow.

I’ve got a flood and drain setup and I set the pH to 5.8. The plants were growing slowly and they had deficiencies even though I was using good nutes. I let the pH drift to 6.1 and the plants started growing better. Is it possible that some plants prefer a different pH than the standard 5.8? I...

I don’t want it to flower. This is supposed to be a mother.

I still don't know the problem. I've used Canna Aqua nutes. I'm using Dynagro Foliage Pro now @ EC=1.5. My tap water is very soft. My Blue Lab Truncheon shows no reading from the tap. I've added CalMag recently and that has seemed to help. Still lost

Believe it or not these plants have been under 24 hour light forever. I don't even have a timer connected to the light. It's very strange. When the original plant was a seedling it had fan leaves with 3 fingers.

The frequency is 1 flood/ 2 hours. I've got an ORP meter that I use to keep the potential at ~500 mV. That usually means 0.15g of 65% Calcium Hypochlorite pool shock every 2-3 days.

Anyone know what deficiency it looks like? Disregard the size and weird fan leaves. If I can fix the environment the leaves should return to normal.

I think it’s GSC. I’ve read that they’ll grow single blade fan leaves when they’re stressed.

I started this grow in December. I cracked a few seeds and a few died along the way. I've got one plant left. It's a clone of one of the originals and it's been through a lot. All my plants that died started to look like this. The plant in the photos just got this big. It had been tiny for...
