Please look at pictures and help with issues

My last thread had died before I got a a chance to update it with better pictures.
1st grow. Using GH flora series.
I use tap water with a base if 82ppm. I was hitting high ppm's in the 1100 range and started having more issues. I vegged for almost 60 days since it was over watered a little and stunted it's growth. Once it bounced back and looked healthier I switched to flower.

I've always had leaves that would crisp up on me that started at the bottom and moved up. I would clip them off but then stopped doing that after reading about it. Now it seems to be just the canopy but I'm pretty sure there's something else wrong other than just heat stress. The pictures are in week 3 of flower from first sign. I just backed the hps 600w off to about 20 inches.

Ppm's are between 380 and 450 now. I did use 1/4 dose of big bud but nothing else other than worm poop tea.

Please help!! Lol

What are the 82 ppm made of?

I don't know. Can link the water report I received but it seemed to be missing some info.
Haven't used any calmag as it didn't seem to point to Cal or mag issues

Just at a glance I would say you have heat issues as well as nute probs

I used GH Flora 3part and liked it. I was in soilless pro-mix hp. What soil are you using? GH 3part is for hydro. I don't know what the implications would be to using it in soil.

It looks like nute burn. What quantities did you mix to get to 1100ppm? If you want to compare what you do to what I did, I followed the so-called useless schedule. (<<link). If you mixed similar quantities I'd suspect it has something to do with the soil. For example, built-in nutes? Or, did you water for runoff? I usually got 20% runoff. If you didn't, maybe salt buildup.

I don't see any evidence of heat stress.

This is in DWC tubs. No soil here

Oh. You said you fed worm poo tea. Is that common for hydro? Do you have any slime problems?

No slime problems. Tea is very common in hydro. Using the heisenberg recipe with zho powder and worm castings.

Thanks for the responses all. Doing a complete flush and keeping the nutrients really low.

I really want to use the big bud and then the bloombastic towards the end. Hopefully I can do that and be alright.
