Yellowing too soon?
What do you think about the yellowing on the 6th week? The npk of the soil i use is 9-2-2. But its the king of yellowing when she needs more N. No dark spots, no burnt tips. This would be normal maybe on the 8/9 week i think.

PH-Problems in Soil
Before repotting, the pH value in the soil has always fallen to below 5.5. The plants always have an iron deficiency. I then repotted the plants and that worked well for 14 days. Now they are showing PH deficits again. The soil has PH 5,4 -4,8. What could be the reason?

Airy buds or just genetics?
How does my bud development seem to you? Trichomes aplenty but I feel the leaf to callyx ratio is pretty poor? Perhaps due to something I've done/not done, or simply a predisposition of its genetics? Trichomes still 90% clear. Likely to fatten up in next few weeks as trichs turn?

Possible deficiency?
Am I correct in thinking this is calcium and manganese deficiency? Do I solve this with a little cal-mag? All spots are on new growth so its immobile i think, Cheers people, happy growing and stay green ✌️ 💚 👌

Spots and discoloration on leaves.
The spots and discoloration are an issue. I'm in living soil and this is a Gelat.OG autoflower. Everything is dialed in near perfectly. Just the spots. Would this be the start of senescence? Any help would be greatly appreciated.

Homemade inputs???
What do yall think of my diary? All homemade inputs, I invest literally less than 20 bucks in my inputs in the entire grow. I want to prove to you all that you do not need to drop money on bottled nutes, remember bottles are for babies. Challenge me? Just look at my diary

Yellow spots
Did these yellow spots appear on the plant, only on this one, could it be because of dry soil? Or lack of NPK?

Hungry? N deficiency?
So this sort of just happened overnight. Plants were very thirsty this morning and noticed a handful of leaves that are fading. I fed them 1tbs of dr earths flower girl and 4ml of calmag in a gallon split between the 2. Should I add some of their 4-4-4 as well?
