So, i have 2 strains here, both fem. Autoflower. 1 is Ak47 and the other is Amnesia gold. (seeds bought directly in the netherlands)
I germinate them in soil,i put grow them in the little box under fluorescent tubes (t
2x 2700k, 2x 6500k each 18w of light. They grow fast and perfect in this little box, high humidity(65% +-), constant temperature 22 celsius , and good ventilation.
As soon as i see roots popping up at the bottom i repot them to their final pot (i know , repotting auto's isn't reccomended but they don't stop growing at all the way i do it). And they go in the bigger growroom under a 250w HPS, with cooltube & big extractor fan to suck out hot air and rapidly refresh the air in the room. But after a few days i noticed, once again that the new growth is not that good anymore. Leaves are very long and pointy, the tips start to yellow and this morning i noticed ''the claw'' on some leaves. The odd thing is that the ak47 is doing this much more than the Amnesia. So it might be genetics? either way, i use seedling soil with very low nutes, i didn't add any nutes so far cause in my previous grow i had definately given too much nutes... when i feel the soil is dry, but not completely dried out i'll water them. i put in like 1l of water, let it sit for 1min, and then i'll add water untill it starts to run out the bottom. then i wait untill it's all drained and put them back in the growroom (this way i hope to avoid dry pockets of dirt)
After hours of searching on the internet and forums, it seems to be N toxicity. but without adding any nutes, and having them grow so vigorously in the first 10days, it seems unlikely to be N toxicity. But what else can it be?
My ph is always between 6.2-6.5, and environmental conditions are always stable....
I hope anyone can help me find the cause for my plants reacting so diffrent. The only thing changing is the humidity and lights.
I hope the pictures are clear enough.
Edit : lights are currently 35cm above the canopy. (250w hps in cooltube)
