Hey Celtic, you are one of my trusted sources on this forum and I didn't really know where to start with this one. I'll throw some pics at the bottoms but I am having some issues in my ebb and flow buckets. I can't really tell if it is a nitrogen toxicity, rootbound plants, pH or nutrient lockout, or a combination of several things. They were vigorously growing until about 2 weeks ago when they stopped suddenly, mostly still dark green, roots were totally white until I started giving SoulN to help them get their stretch on, problems started about a week and a half after starting Soul N supplement. I have 3 large plants and 3 small plants all in 4 gallon flo ebb and flow buckets (Greentrees Multiflow system) so I'm not really thinking rootbound since both ages are showing similar signs.
I did find Thrip larvae in my reservoir and treated accordingly with Bacilus Thuringiensis (israelensis) in the reservoir and am on a regular
spinosad regiment every 3 days.
Large plants were getting 1000-1250 ppm (700) and small plants were getting 900-1000 (700) until I put them both on the same res and gave each 1100. This is really when I started seeing issues.
Running GenHydro 3pt Flora series in a formula known as SPURS.
The formula is
Protect-2.5
Micro-5
Grow-5
Bloom-7
Epsom Salt-.5 grams per gallon.
I have run this formula at different strengths for years for both veg and bloom with great success. Now I'm running into this and it's throwing me off a little bit.
Note. First time using SoulN on a regular veg regiment. I have since cut it and have been flushing them for the past 2 days.
