Yellowing leave tips and clawing down, do I need to start giving more nutrients?
Hello all, I'm experiencing some yellowing leave tips on newer growth, it is paired with some light clawing (downside) on the newest leaves (only on the green gelato). I have used very little nutrients so far and have fertigated only once in fear of giving too much.

Please tell me why the veins of the leaves are so yellow!?
Please tell me why the veins of the leaves are so yellow!? what could it be? zinc block or cal-mag shortage ? pH all the time was 6.3-6.5, EC first was 0.7 today when I saw the yellowness on the leaves I lowered the EC to 0.5

Organic dried fertilizer and supplements?
I’m trying to go 90%-100% organic with dry amendments. I’m also possibly trying to use some bottle nutrients for supplements as well things like Terpinator I would like to use. So my question is; what dry amendments and supplements have YOU guys used and prefer in top dressings.

Hot Soil
Is it true that hot (nutrient rich, in this case organic) soil can create nutrient lockout in seedlings? Next time I should only start in jiffy pellets or similar?

Liquid oxygen
Would you all use this in your water when trying to give oxygen to the roots? I’m noticing some really dense, not drying up that quickly soil so it’s making me think that they can’t breath. I don’t know, just making sure every part of the plant is happy & healthy.

need exact details on making DIY egg shell fert, (how many eggs per how much water, dilute ratios, effective dose etc, using minimal eggs and vinegar.)
How many egg shells do I need to make an effective CAL fert? Are 6 shells soaked in 500ml of water with 1tsp of vinegar enough? What about if I boiled them in plain water? What is the dosage, ratio, and minimum amount of vinegar to use for this process, so it doesn't smell
