Hi Everyone,
My first grow in 20 years.
[2x4 tent; 2x135w HLG @ 36" ; Pro Mix HP ; pH Perfect Grow/Micro/Bloom @25% strength ]
May 7 - seeds to rapid rooters
May 11 - into v. small pots and given 25% pH perfect
May 18 - first watering after transplant, again at 25%
I've been monitoring temp/rh constantly and when lights are on I've been 75f/60-65% humidity... VPD kept 0.6-0.8 with lights on, and it drops closer to 0.5 when lights off (70f, ).
KNOWN ISSUES - my tent wasn't set up right away, and so the seedlings didn't get proper light until May 12... they were definitely stretching for light until then and looked thin.
I BROKE THEM? - I needed to add some support to a few of the plants (I have 13 seeds popped) since they were so leggy... I had read that they need the stress of the environment to help them adapt... in other words, I thought I should add more light breeze to them, thinking that this would "require" them to thicken up and strengthen to be able to withstand the breeze. BUT I can see now that they might have suffered some wind burn from my intervention.
SECONDLY - a few of the plants seem to have some slight yellowing. I've looked online and the most likely culprit for plants this early in growth seems to be improper PH. I haven't measure PH at this point... just using tap water (which is generally good I am told by the grow shop) and the pH perfect nutes.
Any help appreciated.

your plant feels nutrition deficiency. but in this stage soil is enough. incorrect ph couses this
