*EDIT*: Sorry, new user. If an admin would find this post more appropriate in the "Sick Plants and Problems" section please don't hesitate to move it. Sorry! Hey guys, So I'm at (Hopefully) the end of my first Indoor grow. I grew this plant from clone in a Bubbleponics setup I built myself. It's currently at day 22 of flowering but as you can see the leaves are yellowing/dying. The plant in the first image (yellow one on the right) was removed due to root rot. The one that remains hasn't got root rot yet but the roots are definitely darker than they once were. I've tried washing the resovior out with clean water, I've tried AquaPro SludgeAway, Im not sure what else to do. Please help experts! Some info on the grow: 600w MH/HPS Light Air-Intake/Outtake controlled Av. Temp: 22-30C Av. RH: 35-45% Grow Medium: Rockwool/Clay Pellets PH: 6-6.5 Lighting: 12 on/12 off Here's the grow as of today: Thanks in advance!
Re-flushed the reservoir with sterile measuring tools and dropped in a few mls of this: Aquapro 500ml Bionatural Sludge Away and a light spray with a foliage spray iron chelate + willow root mixture 2 days ago. Roots looking white again
Are you running any beneficial nutes for the res? If not get a bottle of hydroguard and use 2ml per gallon. What are the temps in the res? Try and keep them under 75 degrees. Anything over that the water gets warm enough for bad bacteria to grow causing root rot. How high are your lights? Looks like you may have light burn or a possible mag/potassium deficiency. Also what nutes?
Res temp is averaging at 17-20 C. Hydroguard is hard to get a hold of down these ways but I found a similar alternative. Lights are 600w HPS on 110% about 35-37cm from the top of the foliage? Nutes are RX grow+bloom a+b with a 50% dosage, although i gave them some vitamin b-1 root nutes with some nitrogen? they look a bit better but they've definitely seen better days :\
I know people have different opinions as far as trimming dead leaves but as far as im concerned as long as they're not main fan leaves and if they're so wilted up that the pull off the stem without much give then they're draining energy. Looks a bit happier today. Temps been lowered to average of 18.5 C edit: sneaky dehumidifier to the left also
