Is this a Cal Mag deficiency?

  1. Watered 3 days ago with nutes 1/4 strength after flushing about a week and a half back... now these deficiencies have begun to show... is this due to cal mag deficiency or toxicity? Strain is liberty haze barneys farm. Using distilled water. Using cal mag + FFOF nutes in FFOF soil.

    You guys think I should (for the remainder of the grow), put the smart pots inside larger smart pots and fill them with soil? I heard the roots grow straight through and with 2 gallons of extra soil, I'll need to not only water less, but also less to no nutrients. Could this stress the plants in flower?

  2. Advice guys? New growth is showing clear Ca deficiency but I watered with nutes 4 days ago... FFOF 1/4 strength and Cal Mag half strength. Could it just be due to a little underwatering that Ca wasn't able to be taken up? I don't want to add more nutes to add to the problem.

  3. You gotta check the ph and ppm of your distilled water & nutes. Ph fluxes cause backwards intake of nutrients and some dont get used by the plant if its too high or too low. A def. also can happen a lot quicker using tap water with nothing in it but un useful crap depending where your from.
  4. I was using tap water a while back but switched to distilled which has a 6.5 pH. After nutes, I always pH with general hydroponics kit to 6.3-6.6 before adding to the soil.

    I've heard underwatering can contribute to lack of calcium uptake?

    more likely overwatering will cause more problems and stunted plants. If I underwater my plants than they wilt and die. My hydro, if I overwater them I added too much nutes and they are locked out and only drinking water. If I dont water hydro Im sure the nutrients will build up and cause burn.  I would say flush & use like 3/4+ strength cal mag but don't use a toxic amount. I water again with plain water just to make sure too many nutes dont sit the soil.
