Thanks for checking out the page. With the plants getting closer to the end of the plants cycle deficiencies will start to occur. Believe it was a calcium deficiency. it stopped on the other plant after i added my own batch of calcium. I use epsom salt as well. Cal mag is a must if using fox farms ocean forest. I used water all through veg. 40 days. But the 2 plants look entirely different and it could be more genetic than anything. Im not too worried about it right now as im nearing the end. Never used hps. Friend runs 2000watts of hps and ive seen him go through a cpl of harvest with awesome results. I just started indoor growing and i just wanted to use a light that would be effecient in my 2x2. after all the reasearch i did i decided to build my own with affordable cob lights. And ive beem running them for almost 2 month and i love it. Figured having a smaller setup would cost me less. But i have a 18"x 3foot veg cab and a 2x2 flower box. The flower box is where all the money is at the veg cab is pretty simple
