Saggy Leaves

Alright here we go.

First Pic: My setup. 30 gallon res filled with about 25 gal of water filling two 17 liter (I think) bins holding 5 plants each. Well now 4 each since two died from each side :mad:. Each plant is in a 4" (I think) net pot.

Second Pic: The left bin. The front one looks like nitrogen toxicity; deep green with burnt edges and tips. The newer growth doesn't show the same burnt tips, so I think maybe the higher percentage of base nutes helped. The middle one looks alright and is probably my second best plant. It has some old pH burnt leaves from way back, but has nice looking buds and hasn't really had any problems other than the 3-4 days I was gone and the pH was high. Then the one on the back left is my huge yellow former mother with tiny, dense, heavily frosted buds. Not much mass to any of them but damn they are crystallized! Unfortunately, the leaves are all turning yellow and are drying out. It is also a week behind the other plants, so I think its at day 30? The back right one doesn't seem to have any problems as of yet.

Third pic: Right bin. Front left had/has some kind of severe problem, I suspect nitrogen deficiency. Middle plant has what looks like the same nitrogen toxicity as the front one on the other side. The back right one is probably the worst of all the living. It is the one I thought was going to die after developing the same saggy leave thing, but it seems to have leveled out and just looks like hell. The back right is probably my best plant. Big dense crystallized cola and nice looking buds throughout.

So tell me what you think! :jointsmile:

Jeez....they look like an entire encyclopedia of different issues.....I've never seen such a thing. Have you flushed?

Yeah, I flushed a week and a half ago for an entire day and then started over with 800 PPM, then like 5 days after that I got the new res and did the higher PPM base nutes. Then just yesterday I did strictly bloom nutes. I just don't know what the deal could be. I have almost considered trying soil just to see if I can have some better luck because it seems like these hydro plants are really finicky and they all keep getting different problems at the same time so trying to correct one could fuck another one up further. Its just frustrating!

Deja seriously you are an exception from what I can see. I am just completely baffled by your issues and am completely lost as to why your plants are showing everything from nuteburn (and you are right....it sure looks like nuteburn) to every single deficiency ever noted in an mj plant......and few that look pretty good along the way. I just don't get it. You're not in some sort of hydrohut thing are you?

I'm going to be going to my hydro store in the next few days and i will ask my hydro guy in depth and see what (if anything) I can come up with.

Oh and to pass info along, what kind of lighting, and media are you using and how whats your watering schedule?

I don't know what a hydrohut is... so I don't think so? I hand crafted my entire set up including the room, so nothing I have is premade, as hydrohut sounds premade. Its also weird that I have no problems whatsoever in veg but about 4 weeks into flower everything just goes to shit. I even have a 13 gal res and have gone as long as three weeks without changing it and I have still not had any of my vegging plants show any problems at all, but when I change the flower side's 25 gallon res weekly they still go to shit. I am just completely clueless.

I am using a 1KW Hortilux HPS bulb and my medium is 1" rockwool cubes surrounded by clay pebbles. Lights come on/off at 8:10, so I water at 9, 12:30, 4, and 7.

and when you water, how long do you water for? You mentioned roots hanging in the water at some point if I recall. Do you still have that going on?

and those are 17 liter....about 4 and 1/2 gallon containers those roots are in?

I water for 15 minutes at a time. The ends of the roots have a little under 1/4" of water left in the bins once they are drained.

I need to think of some way to get the bins to drain completely. When we made the veg bins, we only put the nozzle a couple threads in. I tried to do the same thing with the new flower ones I made, but when I was trying to clean them, I accidentally ripped the nozzle out of the bin and had to switch back to the old ones. Then when I put them back together, I decided I should probably try something more sturdy since I clean them out at 4 weeks and before final flush. Other than that I really don't know what the problem could be.

My only other thought is do the roots have enough room in those bins after they get to a certain size. You mentioned that they begin to crash in a certain order and the ones in the middle do the best.....could the roots be getting large enough in your bins to be getting squished or something? You mentioned the corners.....there HAS to be an answer especially since they are doing great until a certain stage. The reason I think about your roots is that your plants are showing EVERY SINGLE ISSUE EVER and there must be SOMETHING in common. A 4 and 1/2 gallon bin for several larger plants just doesn't seem very big.

sorry, just wondering out loud.....;)
