maybe it's a nutrient imbalance. or 2 days ago I added Cal/mag 0.5ml per 10Liters, maybe it's overfeeding with high calcium? because 1 day later I saw this problem, or maybe overfeeding for 10 days with these levels did this? some other plants the leaves turned yellow and then they dried up and fell off easily, I'm in a drama at the momentYou need to provide details.

This was the first thing I thought of, then the other things, I'm still in a dilemma. Thank youLooks like it might be heat/light stress to me.
good luck
the plant is 11 days oldWhat is your medium and feeding schedule? Also......what's the EC of your nutrients solution?
Looks like coco, but it's hard to tell under HPS light.
whats the temp in the grow room, sorry i tok too long to post my questions and you allready answered a fewthe plant is 11 days old
the environment is inside
EC: 1.2
I'll ask again. What is your medium?the plant is 11 days old
the environment is inside
EC: 1.2
what environment is your question about? sorry .I'll ask again. What is your medium?
They must be clones because they're way too big to be from seed for 11 days old.
Also.......your EC is high.
yes in coco soilIs your plant growing in coco coir, soil, peat, or some combination? Is there a percentage of perlite mixed in? Mick is trying to figure out if you are watering properly, because different soil types need different care.
6 plants for 400whow many plants under the 400 watt sodium?
thats coco, you need more cal / mag when growing with LED , not so much with sodium.
they look hot as Hugo Phurst mentioned above.
can you turn the sodium off and take a pic with the flash please, it helps to see them under white light to get the best picture of whats going on. unless you have a dule ballast and a metal halide light to go with, pix under MH light is better then sodium
and as above, do you have an EC pen to measure the EC of your feeding solution.
you have to feed every watering with coco, even when fllushing out if youve fed them too much . but seedlings don't need a strong feed, your better off feeding at half or quater strength, and feeding more offten as i understand it.
but im no coco grower, so ill bow down to the coco growers on this one
then should i rinse my plants with plain water ?You should be feeding daily to substantial run off.
Never let the coco dry and never use plain water.
and finally what do you think about what has happened to my plants? heat stress? too much nitrogen? too little nitrogen? or too much potassium? maybe they are now unbalanced and we can't draw a conclusion? I believe rinsing the plants with normal water will do them good?You should be feeding daily to substantial run off.
Never let the coco dry and never use plain water.
thank you very much for help !no , never with plane water as fa as i understand it, you just flush them with a low . very week nute solution, you don't need to flush them that offten, you will starve them and suffer slow growth
