What ever you are doing, keep on doing it !!! wish my first grow looked that good at 35 days !! Mind you i never grew in out of a Wc toilet, with nutrient flushed !!.................. thats not bad for a plant grown in a toilet bowl.......... you are giving me hydro idea's !!!................
The lighter green growth at the top (The New Growth)........ is just a little nitrogen short, as the new grows shoots up, it cannot keep pace with nute delivery................. hence the slight lighter greening on the newest growth............. proves light power is bang on, as is the room and soil temp....................... and feed amounts at correct Ph'es............... looking all sweet there at the mo !!................... 10/10 for a 1st grow i would say....
A lot of thing are correct to get this outcome of normal somatic growth coloration,................. is like, right on the sweet spot at 35 days................... do you use Ec & Ph pens to buld nutrient profiles ??......... if so what is your current veg Ec ??................ if it's 12wks 85 days, that gives you 50 days to finish autoflowers off. They are right small at day 35, i recon this is a 100 day auto looking at day 35 flowers ?? more like 14 to 15wks to % amber.....ALR
