2 grow rooms but

[Dodoman7642]

I have made a nursery to grow seeds and clones and I am good with that but as soon as I put them in the 4x4 tent the leaves start turning yellow the tips look burnt this was my 3rd time growing and I am losing alot of money. I get so frustrated. I have been told I am giving them to much love but the Last grow I left the Lemon haze just watered when they became dry and the same thing happened. This time I bought Critacal Kush and I had a laughing Buddha. I really hope this lot survives. They still in packet at the moment because my friend said she got some cuttings I could have yesterday so wait a few more days to get everything cleaned I also bought ph down after resting my water and ph was high. I bought a room temperature gauge. Just need to clean tent just in case it could be mold or bugs.
Any thoughts as to what I am doing wrong.be grateful. Would n

I think more info is needed. Grow medium (soil/coco/DWC)? Light (and how close to plants)? Nutes (and how much if any)? Photos can also be a big help.

We'll get this figured out.

Buying ph down after your crop dies is supposed to do what?

I think it's for his next attempt.
