I have been vegging these 6 moms in a container for a while trying to tweak them and get it perfect. I have a mini version of the setup that is in a non air conditioned tent and the room would get up to 86f and water around 84f. I been using bennies in the veg and flower on those plants and they are crushing it! So where these are being vegged they are in ac and I had it running 75f and they looked the same as they do now. I thought well Im having success with bennies at higher temps maybe the higher temps get them going/activated more. So I raised the room temp to 80-82 and water is 80f. I have an ro system that im hooking up in a couple days once I get a pressure reducing valve, tap psi is 97, but after I looked at my city tap report I dont think im locking out calcium or mg with my nutes. Running masterblend 4-18-38 with calnit and mg at 2-2-1 ratio. My tap usually reads from 180 to 240 and I had their res at 550 ppm and the ppms were stagnant with ph rising from 5.5 to 6.2. I was getting some leaf twist on the smallest of the 6 and the larger plants got funky looking new growth on the top branches while all the lowers werent affected badly. I had to readjust several times and now ita pretty stable rises .1 or 2 a day. I lowered ppms to 500 to get them to show they are eating and I started seeing them drop it by 5 ppms a day it dropped to 480 and I wanted to add some more bennies and that brought it back to 500. I need help from the pros that have seen this themselves or came near these problems and has an idea. In the smaller tent with 84f temps has low humidity between 40-50 and the ppms were kept low to see when the small plants ate and never went over 400ppms. Im not sure if Im locking out a nutrient or my plants that look rough need higher ppms? They have some leaves that are really dark like nitrogen tox but I domt have a lot of N I have a lot of potassium in this mix was thinking to possibly use masterblend only for flower after week 4 and use jacks 5-12-26 to veg and early flower. Im not sure what a potassium tox in my environment would look like. It could be heat or light stress running 100 watts of cob over them about 5 inches above. Do I need more wattage or are they too close im not sure. Im stumped and ready to try the RO but I think the biggest thing thats only going to change is ph swings from the bicarbonates. I’ll attach pics and order
