Hmm you said the leaves are canoeing and I think that could be due to acouple things. Any heat stress on those ladies. I know when my girls canoe its either because they need alittle N or heat stress. I was using the calmag in the water part of the schedule however since yellowing has started I began adding her to the feeding cycle as well. I am using new grow tech products they seem to need alittle more N during weeks 4-5. That is most likely why they are yellowing abit. How growth slowed?
