18) Do you foliar feed? If so, with what, how often, and at what time do you spray? I started doing this yesterday.. a very small dose of FF grow big misted on the leaves out from under the light, placed under the light when they dried

22) Have you seen signs of insects in the growroom? Thought I might have had whiteflies because of little white specs blowing off the leaves.. holes in leaves as well, but I dont think they could have been caused by flies, sprayed with azamax twice

24) From seeds or clones? seeds
25) Is this an autoflower strain? no



Hey everyone, I'm new here and this is my first grow. I've posted on other forums but have not really found any type of solution to my problem. My plants are now 1 month old, they are under a 250w MH in FFOF. Ever since the very begginning there has been pH problems. At first my pH was much too high and the plants were growing with mutated crazy looking leaves. I went and got a liquid test kit and began to pH down my tap water. All was going good and the plants seemed to be doing a little bit better, they always had yellow leaf tips even though I wasnt feeding any nutes. I decided to buy a cheap milwaukee test pen. This was a big mistake. I properly stored and calibrated the pen, but always wondered why its readings didn't coincide with my liquid test. I first noticed something was up when I had to add about 12 drops of pH down to a gallon of tap water to get the pen to read in the 6.5-7.0 range. With the liquid test kit, the indicator solution would turn proper color after 2 drops of pH down per gallon. I trusted the pen instead. My plants began to curl at the leaves, new growth started to come in twisted and ripped, the new leaves began to grow in extemely pale yellowish and blotchy, the bottom leaves are dying, and the middle leaves are getting rusty. I tested my pH runoff with the liquid kit, it was red, so I figure it is wayyy too low. I flushed my plants with some tap water that I added pH down to because I thought it was too high for the flush. After the flush I gave them their first feeding of nutes.. I did this because I thought the flush would have leached any nutrients out of the soil. I then realized that the pH down water + nutes I fed them probably further lowered my pH, so their next watering I flushed with just my plain old water straight out of the tap which has a high pH. Their pH is still low and they are looking very nutrient defecient. What can I do to save them?? how should I water? I was thinking maybe watering with straight purified drinking water from the supermarket then alternating with my tap water + nutes (this has a lower pH).. would this stabilize the pH?? The purified drinking water probably has a high pH.. I think maybe it would raise the pH of my soil, then I would give them the lower pH + nute water the next watering to lower the pH for their uptake so they are getting the full range of pH. Any advice??
