I got a new TDS pen because I managed to drop my other one in water and killed it. I decided to pay a little bit more and get one that's a little more accurate. Using three different readers in three feedings gave me doubts about lockout so I gave Chocolate and Orange another 500ppm feeding. Deficiencies got worse immediately so I'm going to flush them all tomorrow. Run off pH has been between 6.2 and 6.5 on all of the plants so I'm sure pH isn't the problem.
Everything is getting very frosty and as long as I don't drown the roots in salts any more than I have it looks like things are going to bulk up nicely too.
The Orange Gasm is a well known Nitrogen hog per Jeff Rasta (Irie Seeds) and needs ALOT the first 3-4 weeks of flowering. Your plants look light, and I'm guessing you need more. Just a suggestion.
