Hey guys, I recently started my first grow about 3 weeks ago starting from seeds. Everything so far has been going pretty well and I admit learning through experience is the best way to learn.

I have a 48"x48"x80" Secret Jardin grow tent. I am using an air-cooled 600 watt HPS light with the stink bud aeroponics system.

Recently, I learned that I wasn't suppose to be feeding the young plants with any nutrient, but for the first week I gave them 400-500PMM of Botanicare mix. I am following stinkbud's mix by mixing together 250mL of Cal-Mag plus, 175mL of Liquid Karma, and 550mL of Pure Blend Pro. Then I obviously pour in the mix until the meter reaches a certain level of PPMs. Anyway, the plants were looking great until last Saturday these yellow spots that look almost rusty started to appear on the plants.

On Friday night, I flushed out the system and I am now just running R/O water for the past few days, however the spots have appeared to the second set of leaves. I have tried researching all of the forums to locate the problem, but it seems like the closest problem is nutrient burn, however it has been since Friday since I have flushed out the system. My pH levels have stayed between 5.6-6.2. my water temps are around 76-78 degrees while the temps inside the tent itself have been around 78-80 degrees.

If any additional information is needed please let me know, I'll be watching this post pretty close. Thanks for the help! I'll post some pictures.

P.S. the two strands that are having trouble is Chocolope and Super Cheese. while the third one with the ruffled up leaves is blue berry headband! once again thanks for your help!!!

Well it looking like some over heating by the way the sides of the leafs are turned up as for the spots sometimes it happens dose not look to bad. I just about always have 1 or 2 hydro clones that will start out looking a little sick with all the others looking awesome, they grow out of it most times as long as your doing your job right PH 5.8 is what I like for rockwool and coco.
good luck.
