DAY 57 The plant is doing well and keep plumping. Watered her with 4.2 L of water with a very humble amount of nutes and BTI. PH in 6.6, PPM 600, first PH out 5.7, PPM 750. WIll continue with my strategy of lowering the nutrient amount and giving it more water with higher PH. The rusty brown spots started appearing on upper and some mid leaves more quicker, but it doesn't look as anything serious as majority of leaves are unaffected. Hope that I can fix it or at least slower it until harvest. The only way out seems to be stabilizing that soil PH. DAY 60 Changed colas positions and LSTed it a bit more for better light penetration. The brown spots are still there and keep appearing bit by bit and some upper leaves began showing the signs of burn, but it's not massive and she's filling up. How do you see it for day 60, people? DAY 61 Topped the soil with around 3 teaspoons of dolomite lime and watered her with around 3.8 L of water with PPM 230, PHed to 6.6. The first runoff PH was 6.2 and PPM was 540, the overall PH and PPM of runoff (which was a lot, around 800 ml) was 5.6 and 880. Not bad but could be better. Let's see if that helps to stop the yellowing of top leaves and brown spots. DAY 64 The yellowing and drying of the upper leaves is progressing pretty quickly, but mid and lower leaves in the shade are not affected. The plant is growing alright though, maybe just let it be as the harvest is in three weeks? What do you guys think?
