paper or lettuc wrinkly leaves, all green, rockwool.

Ok, I ask this cuz i am accustomed to nute burn, the brown edges and tips. Other problems with brown leaves. I have also seen overwater, and the ocasional brown leaves and drooping. This time in rockwool I was worried it might be overwater. I backed off the watering. I was doint rooted rapid rooters in 4 in rockwool once a day. Now mabe once every other day until they reach a month.

I am using gh three pack with hardwater micro and tapwater. The ppm is about 700 on a hanna pen or a .5 conversion.

5 plants. Three are doing good. Two are not. The have wrinkly, green, lettuc, uneven with mountains and valles in the leaves. Growth is ok.

I have looked around and maybe the nute str is too high. I am wondering if any other riu members have seeen this before I dilute the mix with more tapwater.

I am hoping the healthy plants, a pw and a herijauna, and an el monstre are female so I can clone them. The messed up pw and herijauna are prob m females tho. lol.

I am bumping this to help anybody. A week of feeding at lesser ebb times, three minutes once or twice every 24 hours at the same ppm has begun to fix this plant, the pw with the weird wrinkled but green and unburned leaves. Also the herijauna that was stunted has also begun picking up.

I kept grodans advice that if their is a prob do not flush with plain water but to keep watering with the right ppm nute solution. I might have done a res change and used the exact nutes as the gh web site calcualator but formuating it to the reg str solution.

Rockwool is a dance to get it as dry as you can but feed as much as you can. Fifteen minute floods last a day min even in flower (2 4 in blocks stacked on each other) and five minute floods can 2 maybe 2 in a 24 hour period and acheive max growth.

THis is my best run yet. No burns and beauttiful green healthy plants. I attribute this to tapwater with chlorine still in, no 24 hour grace period, and GH three part with hardwater micro, using the gh nute calculator. I am using the lucas formula in flower of 8 16 tho, that is less N than GH. I might have to tweek that.


CG to me, My biggest herijauna has sexed for sure female at just over three weeks! PW has yet to begin sexing. El monstre is one of m most exciting tho, as she is growing faster than any and at two weeks looks like everyone else over three. She also has a fruity, lemon combo of bubblegum smelling notes. Very cool. GO SANNIE!!!!!!!
