Ok hi so this is my first grow, I'll start with the facts of my set up before diving into my problem and providing pics. I've got an 8' x 4' × 6.5' tent. Running a recirculating deep water culture, 30 total gallons, 6 sites 5 gallon buckets. Running 8 airstones (1 per 2 for reservoir), a 550 gph submerged pump. Plants are under 2 600 watt air cooled hps and side/top lit by 6 100 watt cfl and center by 3 200 watt cfl. Water temp varies but I'm usually consistent with ice and keep it between 66° and 73°. Ph is kept between 5 8 and 6.0. Feeding general hydro nutes, (most recent feeding 4 days ago 150 ml micro, 150 ml floragro, 100 ml calimag, 75 ml liquid koolbloom, and 75 ml silica si.) Water comes from a watermill site ro and filtered excessively so i usually offset with just 3 to 4 gallons of tap water. I have a ppm meter that doesn't adjust for temp but right after feeding it says 900 ppm at 70°. RH stays around 60 percent, ambient tent temp 75 ish and directly under the lights on the floor it's about 79°.
In the pics you can see the back right and back middle have major burning on their fans. I believe this was caused by allowing the nutes to all be used up between water changes. Magnesium or calcium deficiency maybe? I also add 30 ml of h2o2 daily in hopes of preventing root rot and adding a slight amount of o2 to my water. The front middle plants seed came from a sack of what was said to be chemdawg. The other 5 are ppp feminized from nirvahna. The chemdawg is roughly 8 weeks old, while the ppp is just under 6. I did not leave them in a tray long enough it may have stunted their growth slightly also I didn't know to top these. I intend to switch to flower in about 3 weeks is that advisable?
OK so all that said questions, 1 is the fan burns a magnesium deficiency? Note I also foliar spray every other day with the slightest amount of Epsom salt diluted water. Next question feedback on the set up is it legit? Last, assuming I get these nutes right what should I expect for yields?
So anyone out there who can help it would be greatly appreciated, any questions feel free to ask and I'll answer to the best of novice ability.. one last thing when the water ran out of nutrients last week and before the leaves turned I had a day or two of wild ph, could that have caused the leaves to turn? Also when I dump I use florakleen for two hours in between nutrient solutions.
Thanks in advance and sorry for the disorder of my post...also now I cannot figure out how to post pictures it says I cannot post attachments lol gonna need to figure that out to show you all what is happening
