First Grow: Nine Autos in 5 x 5

15/05/21: Marks the 8th day since the first seed sprouted on 7/05/21. Temp has been an issue sometimes reaching 34 C (Hygrometer is in direct light) so I dimmed the lights to 75% and moved it from 30" to 24" above canopy. PPM was increased from 250 to 500 today. I probably should have done this gradually at a 50 ppm increase per day. I tried taking out the drivers from the mars hydro to mount outside the tent in order to reduce temps but the cords were only 3 ft. Not enough length. 16/05/21: 3L per plant 450 ppm Nutes. Plants are growing fast but not looking the healthiest 17/05/21: 2L per plant 500ppm nutes. Leaves are curling up possibly due to heat stress/light being too close. I moved the lights back up to 30" from 24" and dimmed to 75%. Hoping they will recover okay. Iv'e been keeping the AC on during the day and there is enough ventilation in the tent. I put my hand at the canopy and this led light produces quite a bit of heat which explains the curled up leaves. I should have done this before and started at a higher light and gradually lowered. 18/05/21: Leaves starting to curl up ion edges 19/05/21: Startted LST on 2 of them. Accidentally topped a small sub-node on my very first attempt as well as clipped a part of the fan leaf. 21/05/21: Nitrogen Toxicity getting severe with 1.5 ml/: of Canna Nute, Flushed with 07 ml of A+B with 1ml/L Cal Mag
