Am I on the right track and how long does it usually take to recover from this?

JustGrowWithIt420started grow question 3 years ago

If I'm not mistaken I'm pretty sure the plant in the front left is suffering from nitrogen toxicity, was just flushed yesterday, ph was 7.1 and ppms were at 2200 before flush, dropped ph of water to 6.0 and flushed with final flush until I had a ph of 6.8 and ppms reading at 1100

Leaves. Curl down

Yup, it's suffering but ever so slightly. Which is good! You have time to fix before it causes any worse signs that can't be fixed by getting very dark shiny green leafs, which you have not got. Overall your plants look healthy but brother, drop the PH 6.3-6.5 max5.8- 6.3 is more desirable for coco. Soil is more forgiving with PH swings, try keep it in a even balance. And your PPM is like double what your plant at that age should be on. You are prob giving the right nutes and all but are experiencing nute lock, the claw, or canoeing of your edges upwards is an early sign to look out for before N tox gets too bad. Flush and feed water for a few days even a wk if using soil,, less if coco and restart core NPK+CAL+MICRO. Happy growing, good luck.

1 leaf.. but it's more than a "claw"... check petiole .. if vascular tissue is severed or partially cut on stem, that looks like a wilted leaf not getting enough water next to other leaves without any problems... it's good you got ppm down to 1100.. can't hurt. lowering pH will reduce availability of N in the plant. So, i'd hold off on further adjustments and see how this recent action does first. I don't see dark green nor clawing throughout canopy except that 1 leaf... i still think there's just somthing physically wrong with it.. isolated as the symptom is. There is only very very minor tip curling otherwise.

It does look like some nitrogen toxicity to me. Autos are tricky when feeding them as they don't like the same strengths of feed as photoperiods do. Granted the bigger the auto the more it can take. I use this link a lot to reference feeding them. But its not 100% , if it needs more got to give it more. https://www.autoflower.net/forums/threads/med-man-method-feeding-chart-ppm-ec.47856/ As for Ph One grower I know keeps their soil at a tight 6.4 another lets it fluctuate a bit from 6.5-6.8 "this is what I tend to do" anything below 6.2 is bad news I find and over 7 can be a bit to much depending on the solid composure and what your feeding it. Best Of Luck!

Plant won't recover from damage on leaves. Your ph is still a little on high side at 6.8. Potassium and phosphorus with very light nitrogen is what your plants are consuming at the moment for nutrition to develop your flowers.
