This is my first attempt at a medical grow in California. I'm growing 2 La condifential, 1 dj short "flo", and 1 soma lavender. They are all 3 weeks - 1 month old clones purchased from a nearby dispensary in San Francisco. I'm growing these plants for personal use as pain and anxiety medication. It works great for me and I'm very optimistic about the efficacy of the strains I've chosen for myself. The grow is a CFL stealth operation constructed for under $150. You may need to open the pictures in viewer and magnify them to read the specs on the box I made. It uses co2 fermentation, 12v fans for exhaust, odor eliminating cfls(work great), thermostats that will shut it down permanently if it gets over 100 degrees, and its all up to fire code. I'm using 8,000 lumens in veg with mostly 6500k light and a little 2700k for both chlorophyll A and B. When I get to flower, I will use about 12,000 lumens all in 2700k, and I may decide to install a 70watt hps security light and install 2 more 120mm exhaust and intake fans to compensate. My question is, you can see deficiencies in the plants. Without telling anyone anything, except that I've been very cautious about overfertilizing, can someone tell me what their best estimate is as to whats beggining to ravage my plants? Brown edging on leaves, yellow leaves that are new growth as well. Also the 2 La Confidential that are in the same container, are 100 % indica. They started out with very fat leaves, and the leaves are very thin now almost like a sativa. My system is very dry and about 8000 lumens or so on 4 plants and the lights are no more then 3 inches away from any of the 4 plants. Ive heard that leaves will get skinnier if in a dry environment, because the leaves need less surface area to dry off moisture or something, but in addition to being skinny they also have brown/purple edging. The stems are tough as nails as they have been blasted by fans relentlessly, and the growth is optimal despite symtoms. Ive given them all Schultz micronutrient plant food plus, which contains zinc and iron and some macronutrients, but no boron, magnesium, or other trace minerals. The superthrive is meerly a rooting hormone with vitamin b1, and the rest of the nutes are plant food with organic macronutrients in proper proportion, something like 15 5 3 or something. I have not measured ph, but i use bottled water to water my plants; It's not mountain water, its meerly super filtered and purified water. I dont overwater or underwater, and I use supersoil from homedepot. I have had springtails but they are subsiding now and no other parasites or vermin to speak of. Please help.
