Hey everyone,
This is my first grow and having next to no experience with growing, I'd hope to get some advice on my current situation from some seasoned growers.
My setup is a homemade ebb and flow. I have a 20 gallon reservoir, going to a tray with 11 6" net pots. I'm growing all auto flowering strains. I'm also using a 400w MH light at about 18" away from seedlings.
I germinated the plants in 1.5" rockwool cubes over 4 weeks ago. I put them under a 45W cfl on 24/7 for the first 12 days and occasionally misted them and wet the cubes with 6 pH water with a few drops of veg nutes in it. It was on day 13 that I moved the cubes into 6" net pots filled with hydroton. The cube I covered with a small layer of hydroton.
Im growing in a closet which is why also my temps are peaking around 90 F. There is an AC installed in the room, and I do have an exhaust fan blowing air through the ceiling and out of the room.
My strains:
Auto northern lights
Auto Red poison
Auto Berry Ryder
Auto purple kush
The problem I'm having is my plants starting drooping a day ago and now they begun to turn yellow/brown. I germinated the seeds almost 4 weeks ago in rw cubes and definitely feel they've been stunted because of the underlying problem I'm experiencing. I germed them under a cfl on a 24/0 light schedule for the first week then put them in the hydro setup under the hps with a 18/6 lighting schedule. I foolishly added very low strength nutes (general hydroponics brand) to the hydro reservoir, maybe 1/8 strength or so, and don't know if my plants have mute burn or maybe some defeciency. When I added the nutrients to the first reservoir fill, I only used the floramicro and floragro of the three part system. After reading the labels, I noticed that the third part, the florabloom contains a much larger amount of magnesium then the other two parts (5% compared to .5%) The directions for the system also say to use all three parts in equal parts for seedlings (I know autoflowers dont usually follow this rule though).
Do you guys think that maybe since I didnt use the third part, the water was lacking in magnesium thus causing these symptoms?
I'm reaching close to 90 F when the lights been on but now have a fan blowing across light and plants. Temps reach 65 when lightsoff.
I refilled the reservoir 3 days ago with new water after cleaning it out. I only put in fresh water phed to a little under 6. I'm hoping this will help the plants since I've read autos do not like nutes until flowering. The water in before had maybe 1/8 strength floragro and 1/8 floramicro.
At this point I'm really stumped at what exactly it could be. The plants are not showing any signs of getting better after the fresh water and Im torn between so many possible problems it could be.
I thought maybe nutrient burn, then overwatering, underwatering, and then a Magnesium def, but the stunted growth also made me think nitrogen or phosphorus.
Any help would be greatly appreciated!
And thanks in advance for the help!
