Hello GWE, first time grower, started it in a cardboard box lol Then converted a fishing shanty to my grow tent! Started plants in a terrible grow mix from box stores. 2 viperspectra 600, lots of air movement, and a 4"filter/fan. Veg went really well, ex for fungus nats(crappy soil) a little white fungus on 1 plant only(white widow auto). About 3 weeks into flower things started going awry. I have 3 fem AK 47 and 1 blueberry auto, 1 Amnesia auto, and 1 White widow auto.(all were LST from early growth) pH is tested everytime anything is added. 1st pic is AK.(manganese deficiency?) About the same time my autos were showing tip burn so i backed off on nitrogen...now leaves are yellowing up the plant..wth I added nitrogen last water but it was a small increase. Should i cal-mag the AK and just increase nitrogen for the autos? Open for any ideas at this point oh almost forgot, using Root farm and flora bloom. 3-7-14. thanks for reading... homegrown

Hi homegrown, I can't see anything in those pics. Instead of adding any more nutrients, flush them. They probably have nutrient lockout if you haven't flushed them on a regular basis...

Thanks alltatup, i flushed two AKs with pH'd water..checked pH in runoff and its same as water in. I'll let them dry out for a few days and start back at 1/4 Nutes per gallon and see how that works. hg
