Hi everyone!
Been a while since I last visited, but this site taught me a lot. So i'm back with a bit of a problem...
I'm at my 3rd grow and don't know what the problem is. Basically I started 10 Sensi Black Dominas 2 weeks ago and 3 Sensi Afghani #1. These are supposed to be killer quality, (the black dom at least). I'm having severe problems with these and I've never had these problems with seedlings before. Please take a look at the pics. These are 2 weeks old, they're pitiful for that age. Only one showed a 2nd 1 inch real leaves. Others just have the beginnings.
So to give a little background as to what I've been using and still using for this grow.
I grow in rockwool only, had great success all last 2 grows. I use a single 600W electro ballast conversion MH and regular HPS (i use MH for veg and HPS for flowering).
I pre-soaked the starter cubes in 5.5 Ph water as always. I'm using an RO system and I'm suspecting this might be causing this problem, b/c the water is too clean and lacks certain minerals found in tap water.
I'm using Superthrive vitamin, I added just a bit to a bucket of 5.8 pH water. The EC is at 0.03 (that's about 20PPM). That's all. After that I mixed a bit of tap with the RO water to get a ppm of 150-170 which is normal for seedlings.
The temps are constant. 70-80F. Humidity at 40-55%.
The seedlings started fine and slowly started to yellow and the growth totally stopped. There was a good root formation when I transplanted the 1" starter cubes.
I'm not a noob, i used this before. I'm trying to figure out what the heck happened to the leaves, looks like a PH imbalance. What do you guys think? My MH conversion lamp is about 2 feet away (i had it at 1.5). Anyone seen anything like this? What should I do? Please help, hate to see $120 seeds go to waste. (btw my last 2 grows were Nirvana seeds, first time I bought expensive ones and I get this
PS
The two green ones are the newer ones I hatched. They look fine. Compare them to all the rest.
