Are there roots in the res? Im on my first grow as well but when i had droopy leaves i had the water level in the res too high and the roots werent getting enough oxygen. Good luck.

Im not sure what else it could be.. im sure an AFN vet will be in to help you soon. Check out the rest of the forum.. Thats where i learned. But i can tell you that you probably shouldnt be adding any nutes at that stage. I mean i did but all over the forum you see people saying to stay away from nutes early on, so it could very well be a toxicity issue.

Looking good! I have no experience with GHE, but that ppm is more or less 0.6, which seems fine at this stage. I wouldnt worry too much about them, they're looking really good. What is your ambient temperature in there?

 

[Groff]

Seem spot on. Yes, as soon as they touch water, they go hyperdrive :thumbs:

Hi Faquarl, looks like you got moved ok. I would definitely not give upon the injured plant if it was me. Damage looks pretty minor and should recover just fine assuming the roots were not injured by the impact. I would give it a week or 2 and see how it stacks up to the other 2.

BTW the spot on the leaf looks like nute solution burn, don't think it is a reason for concern. Plants look like they are doing well.

Hi Faquarl, I am not a hydro grower so have flagged your post for one of our experts.

Regarding RO water the real value I believe is that it takes the unknown chemicals in your tap water out of the picture that could interfere with your nute solution and makes managing pH and PPM levels simpler

As to the brown spots on one of your plants without seeing pictures I would guess a cal/mag deficiency. Autos in particular those under LEDs are major cal/mag hogs and need a supplement in addition to what is in your basic nutes

Update:
Plants grew a lot in the past days and im pretty satisfied so far.

Back to 150Watt and im going to add 100watt more on the weekend. The third and smallest plant got hit by the fan which fell of xD omg im so angry right now at myself that i can only laugh:Grrr:. The fan cut a leave clean of -_- and i consider to through the plant out and order a new seed.
View attachment 400317 What do you guys think could the plant still yeild or is it wasted effort?
PPM is at 317 right now i´ll change the res. and add a little more nutes to maybe 350-370ppm in the next few days.

I broke the main stem 90% off on a 25 day old plant. An auto to boot. At the end of 84 days, she gave me 168 grams dry!

raise your ppms to 600 ( total ) and keep it there thru the grow. Your plants look good, keep up the good work!

Thanks for the post shotta12,
some of the roots are allready in the res. but the majoity are hanging in free air and getting moist due to the bubbles of the airstone.
May this be nitrogen toxicity? The leaves dont look too green but one plant curls its leaves a little bit. Im using 1/3 strengh of my nutes atm, with a ppm of 277.
These are my roots:

Roots and plants are fine, mine grew like that too. Leave an airspace between the pot and the res water. The plants will grow roots that will absorb oxygen and this will help prevent root rot.
