First ever grow!!

Seem alright. canoeing can be a few causes -- heat, light, nutes... due to auto's being touchy and how lush it is (some tips yellow? hard to see under grow light), i'd say dial back nutes 5-10% and see what happens. After 8 weeks, you have a fairly healthy plant so things must be roughly okay. Just add a little extra water to mix. Keep pH around 6.5-6.8. You have a ton of perlite, so i'd treat it a bit more like soilless grow. This isn't bad. Drainage is great. In general 50/50 is as high as yo need to go. Coarse vermiculite is an excellent option too, as it provides some silica too.

Hi there, Your plant is fined to me in every way.Just one thing, curling leaves due to heat stress.But it is also normal in flowering stage.Plants are less defensive during flowering.Better if you can lower down temp.If your day temp is 22C for sure, then no need.Adjust your water pH to be around 6.5 whenever you water and check run off.Always maintain dry/wet circle between each watering.Maintain temp, humidity and regularly check any sign of problems.Love, Care and Patient.Happy growing... ✌️
