Northern lights 00 seeds Mars ts 1000

Steady growth, did not bother with ph so far plant does not show any issue did use bit of chicken manure so there is a reason of cutting down the nutes but can also say I will need to increase it as the 1st leaves or the cotylons just turned yellow and dry I a matter of days, did 1 more watering after that but I know it will show very soon a deficiency, so planning to increase the nutes a good bit as It will start to bloom.
