hi all. I’m at day 36 3x lsd 25 autos. 3x3 tent. Mars hydro tsw 2000 led. Have been feeding an ph perfect since day 10 with r/o water . 1ml/L micro, grow, bloom. 2ml/L b-52 1ml/L calmag .I was feedinng nutes every feed following a schedule that I found on line was planning on increasing nutes until issues. It’s my first grow. I chose ph perfect as I thought it would be easier. last week noticed a few rust spots on leaves. I thought it might be burn marks from magnified water. Then started to see some new leaves growing a bit weird, twisted leaves.. some leaves with burnt tips, just a few.. I haven’t been ph testing. started giving my plants just r/o water for 3 -4 days then gave more nutes. Nutes made new leaves grow twisted. Ph’d ro water to 6 checked ph of run off today it was 7.2. As I said, this is my first grow..no idea what I’m really doing any advice would be much appreciated. I’m guessing I was over feeding nutes.

Also, what temp and humidity range are you in, night and day? I get those spots when my humidity is high and the plants transpire through the leaves. Where they overlap, I'll get those rusty spots.

Tips look a lil burnt but not bad. You don't want it getting worse though. Curling could be ph related? I've seen it before on new growth, but it just grew out.

when using the nutes i dont adjust ph because it adjusts itself to around 5.6 . I think if i up the ph , the ph perfect buffers will adjust it back, as this solution adjusts any ph to 5.6- to 5.8 ph? I used ro water ph to 6.0 today and the runoff was at 7.0. I was previously adding nutes to every feed. Should i just use ph water for a week to clean things up and then maybe feed nutes only once a week?

I would still be adjusting the ph of your water and the nutes solution to somewhere between 6.3-6.5 for now. Try to get the PH back in a nice sweet spot. I wouldn't feed every watering unless you're in coco. It's hard to see what medium it is, but you said soil I think. Every other watering is fine as long as you are watering frequently. I've done feed, feed water with some strains but it's safer to alternate if you're watering every day or other day. 5.6-5.8 is ph that's good for hydro growing not soil, just in case you were unaware. It seems like they have been overfed a little bit and the ph is probably out of whack as Hollatchaboy mentioned. They should be fine in a little bit if you get those things straightened out.
