Hey all,
Just wanted to ask if it's normal for the lower fan leaves on an autoflowering plant to be dying and falling off with probs about 4 weeks of flowering left to go? They are turning a lighter green then curling up at the edges and dying then falling off, some fall off some come off as I'm moving or checking the plant. The edges of the leaves at the bottom are also browning and curling upwards but some are browning at the tips. I know it's normal for them to dye and fall off towards the end of flowering in a photo plant but usually that would happen closer to harvest time. I have lowered the amount of nitrogen going in quite a bit at start of bloom which was working great at first, was using professor's A&B only during veg which has huge amount of nitrogen so I have cut right back on them and am adding flower boost. I've been doing half the recommended dose flower boost then adding A&B to get to EC target so 13ml flower boost & 15ml A&B in 9 litres. The full dose for flower boost for 9 lt is 18ml & for A&B is 45ml, the npk for A&B is 22.6 - 6.1 - 29.5. npk for flower boost is 0 - 10 - 8.7. Should I go back to doing full dose of A&B and forget the flower boost or do full of both? Really hard to figure out how much of both for perfect blend and with autos I don't want to totally ruin the grow. Been feeding at 0.9 EC, i read that for autos EC is good between 0.8 & 1.0 but at this point I'm so confused. If anyone could help that would be greatly appreciated. Thanks very much.
