I'm my Best Critic

day 21 from seed and ran into a problem: my heat is getting too high causing my plants to soak up more nutrients then normal getting slight burnt tips....until i can get temps down i'll try feeding at half strength....both plants have been topped...the chempie has a good smell coming from it already but is stunted by the heat....the critical is growing a lot faster then most of my plants but it's sucking up nutrients more causing burnt tips....hope i can get my temps down without using a a/c...my only options are going led lights and getting rid of the cmh or buying a portable a/c , just trying to keep them alive until then😐
