Hey guys got something going on with some of my plants and I have no idea what's causing it. I'll try and cover most of the variables and hopefully get some advice on how to fix it.
Area : 4x4x7 Sunhut XL Grow Tent.
Light : 1000w HPS AC Hood, +/- 500cfm exhaust w/ passive intake vents. Exhausts out of tent and into the attic. (Ballast is switchable but I don't quite have the money for a MH bulb, so just vegging under HPS for now.
Temps : 77-79 F w/ 40-50% RH
Nutrients : General Organics
Medium : BCuzz Hyrdromix HP (70% Sphagnum Peat/ 30% Perlite) ("Contains dolomite lime & gypsum as PH adjusters")
Containers : 1 Gal. Grow Bags (Transplanted from Solo Cups a week ago)
Strain & Age : 9 out of 10 are Nirvana Bubbleicious from seed, and the other 1 is Dinafem Royal Haze. They're all about 5 weeks old from sprout.
I'm not very experienced but I've had about 4-5 successful small grows, using the tap water here. My specific company is small and only covers a few neighborhoods here, and they provide "RO Filteration" before it arrives here. It comes out at about 150 ppm, and I just aerate with an airstone for 24+ hours before using, to get rid of chlorine, and keep it oxygenated. Been watering about once a week, with just straight water, PH adjusted to 6.0. They've looked good up until last week, after I fed for the first time.
Used everything recommended in the GO Line at half strength (About 5ml per gallon) last week. (4th week from sprout) PH of tap water comes out around 8.2, after mixing everything, it was at 6.3, so I didn't adjust, fed as is. Runoff was coming out at 5.3-5.4.
Throughout the week some of them seemed to droop, and new growth was really light, so I was thinking it might be an N def.
After about a week (yesterday), I mixed a full strength solution, after all was mixed, PH was @ 6.0-6.1. So again, I didn't adjust, fed as is. Runoff was coming out at 5.1-5.2.
The low PH is really bothering me here, but friends that have used GO in the past, say that's normal, and it's not a truly accurate reading of my medium's PH. The problem here seems to me like overwatering or PH problems though. From what I've read and been told about my mix...it'd be really hard to overwater since its so airy and pourous, and I've been waiting a good 6-7 days between waters, making sure the weight is where it should be etc.
Edit : Forgot, I topped all of these about a week and a half ago too.
