    Severe leaf curl

    Anyone know what causes this?? Every single grow no matter what strain I thought maybe it was magnesium deficiency so have been adding some canna mono 1ml/L since the start of this grow but doesn’t seem to make any difference These leaves will eventually die but I’m only 6 weeks into flower

    Leaf tip curl/browning, nute burn? But bottom leaves yellowing...

    Hello, not sure if this leaf tip curl is over feeding as bottom leaves on plant are yellowing, what do you think? Mr Nice SSH on day 70 of flower, feeding half strength AN Sensi Bloom.

    2 grows with nanners/hermies - could it be my light??

    Hi, in my last 2 grows both ended up with seeds, basically the plants hermied or developed nanners - first time i suspect it was the timer, was a cheap analogue style one where you push in the buttons for whatever hours - i noticed the light was on after hours when it should have been long off...

    Can’t figure out this problem

    Hi, getting this yellow striping on leaves for about 4 weeks, thought it was maybe an iron deficiency as only showing on upper leaves, my ph was maybe around 7-7.2 so made sure it was more towards 6.8 This however did not fix anything. Now some of those leaves are going really brown around the...
