Organic Forum Stomper x Grape Crinkle x2

Nov 2 - Both plants are growing at a good rate (5 Finger Leaves), will need to start LST next week I suspect. Grow room is getting colder, so I'm giving more light until they're more in full veg. Young plant is 4" tall, old plant is 5" after watering roughly 1-200ml when dry. Nov 3 - Watered Younger plant 500ml at midnight. I suspect next water will be Nov. 5. Older plant soil is still moist, so will water heavily (500ml) in the morning. I also suspect 7 finger leaves in the morning to be present. Nov 4 - Light burn evident on older plant, have initiated LST, bent away from light and moved further from light. Also started training some large fan leaves but didn't want to cause too much stress, Younger, Smaller plant I suspect may be stunted from large water intake? Nov 4 - Watered older plant 4-500ml which I suspect will last 3 days. 7 Finger leaves present. Nov 5 - Started LST on younger plant, I noticed beginning light stress on new shoots as with older plant. Leaves were finally praying today, but then I watered - I suspect they'll droop tomorrow, but hoping they'll pray instead. 500ml at 6PM Unsure when last watered, estimate it was the 7th, pots seem close to light. Will definitely water tomorrow, and need to think about amending soil. I'm seeing some paler lower, older leaves but from what I read deficiency symptoms start in new growth.
