ive had these clones around a week now everthing seems to be going ok following a recomended feeding schedule ,
there growing in size fine . one thing is that there are some leaves on the plant what have burn marks on them but not on the ends or on the tips and the veins are green also , i know that i spilt some water on the leaves a few days ago do you think this is the reason why . or is it somthing else help please

the ph has been around 6 .4 , i have also had the light on 24,7 . thinking that you could be right with the heat stress , but not all the plants are like this infact the plant which is drinking the most water looks quite fine

Well then, I don't know what the heck that is. If you have other plants that are doing fine, maybe you shouldn't mess with it. Sometimes clones devour mobile nutrients from older leaves until they're well established. Concentrate on the health of the new growth.

it could be that this clone needed more propagation and has been struggling with the RH

what is your RH?
were these clones rooted when you had them?
what growing medium are you using?

Your plant is showing signs of magnesium deficiancy if im wrong it also could be your plants need misting more often, my clones are kept constantly humid and my fan keeps them strong i suggest ordering a product called anti wilt. it should do the trick. up your misting for sure though they look a bit dry
