Rockwool & plugs both look super dry but we need more info... how often do you feed, what strength, can you shoot pic of nute bottle labels, are you using cal-mag?
I’m soil grower so hydro and NFT are way out there but more peeps will jump in soon.
Hi MochaBud,Welcome to the forum @behnam9537
You got me, I have no idea WTF is going on with those huge ass rock wool blocks, a first for me
...that being said IDK ...looks like it could be a PH issue, or a cal-mag issue, or it needs to fed some veg nutes, or "C" all of the above or maybe I need to go smoke and let someone else have a guess
Hey @Emilya @West Hippie @InTheShed @Buds Buddy have you ever seen some one grow like this before
A new one on me
What i see are leaves tacoing which can be a heat issue. But im inclined to think its a pest issue. I have had similar reactions from mites. Have you examined leaves for signs of pests or eggs. Mites are tiny you might need a scope. 2c happy growing friend.End of wee 6 in veg
Nutrient: Athena pro
Growers choice LED
Light intensity 40%
It's been 2 weeks the growth is very slow and there is not much canopy as you can see in the pics,
Any advice would be so helpful...thanks
Well, I'm just guessing here, cuz I've never seen someone grow in straight rockwool before...but I would imagine it would have to kept moist, at least, and treat it like a soil-less medium (coco or hempy) and PH at 5.5 to 5.8 with cal-mag and small amounts of nutesHi MochaBud,
I tested the ph and ppm of the rock wool cubes and they are at 6.8 to7 and 1500. are they too high? maybe i need to flush them one time with RO water at ph 5.8 and some cal-mag then continue to feed them with nutes? or should i just keep feeding them with nutrients?

Hi Emilya,Hi @behnam9537 and welcome to the forum! Something very basic seems to be wrong here. I do think your plants are hungry and need to be fed every time water hits them. They also look like they are either starving for oxygen (are you aerating the water?) or its too hot in there. I would question the mix of the nutes... just the names say that you should probably be running core and grow at this point, but not being familiar with that nute line, I have no real clue.
Room temp is about 73 to 83. It doesn't go further that 83 cause my AC will start running at 83. The temp flowing between 73 to 83room temp water shouldn't cause damage... might be a great place for pathogens to grow though. Since you are aerating, your leaves are telling me they are too hot... so what is your air temp in that grow area? If it is over 85F, you have a problem with heat.
Exactlyyyyy, that's why I'm confused. I'm trying to micromanag everything as you see I'm still awake (it's 4 am now) but still couldn't find the problem.That all checks out then... I think we need a flood and drain expert in here... but I am thinking along the lines of an earlier comment, that this medium needs to be kept wet, and fed at least a couple of times a day... like a hydro operation.
