madmucka! welcome to the show.
ridges and twists on leaves=overwatering. first thing i see.
purpling in stems and petules=low calmag
but take the whole picture...
ridged bumpy twisted leaves, purpling stems n petules, severely stunted slow growth, mild signs of overfeeding.
i suspect overwatering to be the bigger problem here. when a plant sits in too much water, the root hairs start dying back, reducing thier ability to take up nutes. then you feed every watering, raising nute levels they cant even take up without root hairs. now osmotic pressure reverses in an attempt to balance out, and now you have the "lockout". and roots continue to die back as fast as they regrow!
try waiting to watering them until the pot feels about half or third the weight it was when you first watered, instead of trying to put nature on YOUR schedule. super common mistake.
also, dont feed with every watering. try using half strength of whatever you are using, and give it to them every other or every 3rd watering.
remember... damage from too much of ANYTHING costs you 3 weeks to fix, and hurts yields at the other end.
a DEFICIENCY can be fixed in a week. less is ALWAYS better and safer.
get this plant going again by:
1. let the pot lose about half its weight.
2. water (only water) till it comes out the bottom.
3. repeat 1 and 2.
4. let the pot lose half its weight again, and this time mix up 40 ml per gal clonex solution and 1/4 tsp per gal great white microbes and water in again until runoff. use this for your feeding every other watering for 2 weeks.
5. after 2 weeks you should have a pot FULL of healthy new roots, and you can resume your regular brand of nutes at appropriate strength. your plant should be showing some nice growth by this time also. if the purpling is still showing in the newer growth, boost your calmag a little.
im attaching a pic of plants 8 weeks from seed to give you an idea of where they should be at this time.
​​​​​​​best of luck!
