Intervenal chlorosis built up in the lower leaves. I assume my soil for germination emptied out in nutrients. Im transplanting for the first time in hopes that the fertilized tomato soil naturally takes care of the problem. Writing this retrospectively.
It took 4 days until the chlorosis stopped getting worse (as can be seen next week). I'm assuming this is about the timeframe a plant needs for it to really get nutrients from the new soil after up-potting? Happy that as a beginner i stayed patient. Worked out.
Might germinate in regular nutrient rich soil the next time, or smaller plugs that get put into nutrient rich soil earlier then when i transplanted. Did not hit a sweetspot.
You can get away with using the tomato fertilizer. Just keep an eye out for deficiencies/toxicities, the nitrogen is higher than ideal and the phosphorus is lower than ideal for the flowering stage. During bloom too much Nitrogen causes problems like reduced yield, underdeveloped buds, lower potency. Cannabis plants love Phosphorus during bloom, not enough Phosphorus also effects the buds negatively, can be more susceptible to diseases and could possibly end with a premature death of the entire plant. P and K are the two you don't really want a deficiency in during flower. They're responsible for a lot of the flower production.
Just some food for thought. Good luck with your grow though. You have some beautiful and healthy looking plants, I've yet to be disappointed by RQS.
@SlamFM, thanks for the attentive feedback. it makes me think.
even though my fert is high in N, i think overall im on the lower end of providing nutrients. this makes me think if i can maybe up the 5ml/L to 10ml/L to give it more PK, as long as i dont feed too much N. study below suggests that you really have to pound it with N for it to have a negative impact on yield. so i probably could up to 10ml doubling PK. gonna sleep on it tho haha.
