Day 43 - Watering 5L (Sensi Bloom Part A and B 4ml/l each, Bud Candy - 2ml/l, Big Bud- 2ml/l, B-52 - 2ml/l) ppm 800, ph 6.6; drained out - 0.3L
Day 44 - I've been having some issues since watering yesterday. The top leaves have dark green spots, some leaves have brown spots, and others have scorched tips. My soil's pH is 6, and it stays at 6 even after watering. I think the low pH might be preventing the plant from absorbing enough calcium, leading to a calcium deficiency and possibly impacting other nutrients like potassium and phosphorus. I'm going to flush the soil with clean water at pH 6.7 and add calcium/magnesium. I'll keep an eye on the new leaves and hope they grow healthy.
Watering 5L (Sensi CalMag Extra - 2ml/l) ppm 250, ph 6.7; drained out - 1.5L, ppm 1000, ph 6, then drained out - 1.5L, ppm 780, ph 6
Day 45 - The leaves that were damaged yesterday have gotten much worse. The dark green spots have turned dark brown. It's not looking great, but thankfully there don't seem to be any more affected leaves. I'll keep watching them. I trimmed off the worst of the damaged leaves this evening.
Day 46 - I removed all the damaged leaves, and also the large fan leaves that were blocking light from the lower flower clusters.
Day 48 - Things are looking up for the plant! It's stopped growing taller, but the buds are getting bigger and trichomes are popping up. The pot's dry, so I'm watering it now. I'm going to cut back on the regular nutes a bit (25%) and add some calcium magnesium (half the usual dose).
Watering 5L (Sensi Bloom Part A and B 3ml/l each, Bud Candy - 2ml/l, Big Bud- 2ml/l, B-52 - 2ml/l, CalMag - 1ml/l) ppm 730, ph 6.8; drained out - 0.3L, ppm 730, ph 6.6
