pics say more than words

New water nutes at 400ppm. 75° tent. Hydroguard and calmag. Water started as distilled. 5 weeks in and the big one is 6" the smallest 4.5". Look OK to you guys. 2nd grow first was a boy and was very big and streched.

How much air are you pumping? How big is your rez? They look nitrogen starved and oxygen deprived. They also look like you could foliar spray them and it would probably do them some good. Maybe fivehundred ppm would benefit them also.

2 topfin air 8000. Right now has 3 ait spiders in 3.5 gallons of water. Pic shows bubbles they cover the entire bucket.

What's the pH running?

Ph is 6

Might want to lower water levels in rez, or had more oxygen. Also check the roots for brown slime. They should be bigger than this after 5 weeks in hydro

ph of 6 is too high get it down to closer 5.5 no higher then 5.8. also what kind of temp is the res water should be between 68 and 72 F.. They do look over watered so yeah maybe drop the level a bit and check that ph bring it down.

pH of 6 is alright. You'd get more N uptake at 5.7-5.8. They look hungry. But the weird leaf curling is the real concern.

Clear air lines are a big no no.

Bubbles look adequate.

Use more hydroguard and buy proper air lines jeez

Yup. I start mine at 5.5 and let it drift to 5.8 then adjust back down

Update. The plants were not responding to anything we tried. So I decided to go back to tap water. Took out the chlorine, added hydroguard, calmag, and then 300 ppm of floraduo. Not much happened. So being close to death I said I'll try one more thing. I pulled the plants out put a 6" air stone at bottom of tank. Then a 6" cylinder air stone in the basket put in the hydroton and plant and filled that bastard to the top with water. And I mean you can see bubbles in the top of the hydroton. The plants shot up two inches and leaves spread open. They drop the reservoir about an inch of water per day. Roots shot out 2" over night. The ph is between 5.3 and 5.8. And raised humidity from 40% to 60%. Water Temps still pushing the limits. But not causing a problem yet. Trying to keep tent at 70°. We shall see...
