have grown outdoors many times but 1st time indoors, in my tent i have 12 beauties of 4 different strains some have signs of problems on the leaves but others r growing great all in same environment in clay pellets under LED(that r working great)
Some strains are more sensitive to nutrient concentrations and or pH fluctuations, and so for example, some strains will not show nute burn at certain levels while others will show nute burn, even at the exact same level.
It’s all genetics my friend. Even though they are the same strain each plant has its own genetic make up.
Thus each plant will react differently to nutrients and or light.
i think that an ideal situation having 4 varieties sounds good but growing @ same time as a novice not so good
