First Grow!!! Hash Plant HELP!!!!!!

Hey all

First let me pre-empt my comments by stating I live in California and am a patient, as is my Girlfriend (were sick together )so the 12 plants in my pics are legal here in the county I live

That being said... LONG time smoker, first time grower.

12 Hash plant clones
400w MH/HPS
GH Nutes
Cal/Mag
2x2 rockwool
grodan substrate
Ebb and flow table
15 gallon res

Using GH nute formula as posted on site in addition to h2o2 and cal/mag
Using r/o water

So far...ok I guess.

Small little problems here and there

I put the reservoir in the tub, installed the table on top of it and use my spare bathroom as my first grow space.

The first pic is right after installation on 9/3

Mistake #1
Cutting squares instead of an "X" on substrate for cubes

Second pic is same day backed up to show room size

Here is them just now, 3 weeks later

I think they look healthy. I overfed them at first, was using tap water (350 ppm's!!) waterered too often, suffered thrugh a few more problems..

ALL FIXED from lurking here...Thanks!!!!


So now they look good


BUT


Having a few leaf problems.


ONE plant, ONE leaf, has lots of "light rust colored stains" the rest of the plant is healthy.

A few leaves have tears in them, no bugs are present


Any ideas???

Im liking the simplicity of your setup.

One potential problem I see is not being able to properly clean out the reservoir, due to the fact that its trapped under the tray. But otherwise, very cool.

I disconnect the pump from the bottom and attach a longer hose to pump which drains to toilet, its pretty easy. I have another attachedment on sick that allows for another hose back to reservoir for cleaning ONLY, its not RO. That I buy from the 25 cent machine at Walmart.

Any ideas on the spots?

Not sure. Maybe this will help.
