nutirents

What's going on everyone. Hope everyone has happy holidays. Didn't see a thread about these nutes so decided to start one to share experiences with them and questions I'm running PBP(pure blend pro) grow, Silica blast, cal-mag, ryhzoblast, hydroguard, and liquid karma (Lk) Is there anyone out...

I'm switching my lights to flowering today and my plants are scheduled for a feeding and they look quite hungry, but I'm not sure by the color of the fan leaves whether to feed them 1/4 nutes or no nutes or what! If anyone could guide me to the best option that'd be great!

I have an obvious nutrient deficiency but i cant figure it out, i believe it is sulfur or potassium but i would love any opinions or feed back on what you think it is and what i should do about it!!

It's day 21 and I noticed that my biggest plant is showing light green leaves and I was wondering if I should give it its first feeding because I'm thinking it might be due to nitrogen deficiency, but idk I'm pretty new at this. I'm using potters gold soil with RO water only. It's in a 3 gal...
