A couple different problems?

Hey guys this is my first post on this forum so here goes nothing.

This is my second grow cycle so I am still very new and am trying to nail down a couple problems I am having in my garden. I just moved these girls into my 5, 1000w DE gavita room and switched them to flower. I am using soil, I'm PHing them at 6.0, keeping the temp between 74-80, rh at 40-50%, and about 1150 ppm. It seems I'm having a couple different issues. I think the top pic is due to heat but I use a temp gun to check the tops of the plants everyday to try my best to avoid that. And as for the bottom two pics I have no idea what it could be. Any help is much appreciated! Thanks!image.jpegimage.jpegimage.jpeg

I'm running a custom mix of nutes. In the last feed I used calmag, silica, a base A&B, roots XL, trace elements, humic acid, Moab, floralicious plus, sweet raw. Maybe a couple other nutes, just naming the ones I can think of off the top of my head

sounds like a mess, you have a deficiency, What I would do is drop all that non sense and just give it small feedings of the a/b, bet you see a big improvement.

Nothing wrong with that. But, how do you know what you're producing in that mix? (You can enter the info from the bottles into this spreadsheet and be aware of the details that result from your mix.).

What soil do you use? You said you ph to 6. Are you using soilless like Pro-Mix HP? If so, it sounds like you're treating soilless as soil. There's another recent thread like that and he's having a similar problem (yellowing edges, acidic soil). Or, you should ph to 6.5 for soil?

Thank you for refering me to that spreadsheet, I will definitely make time to fill that in when I get to my room. I am using fox farms soil... My partner is running the same recipe (has been for years) and has never had any problems with phing it to 6. Wouldn't raising the PH to 6.5 cause them to freak out even more? Just curious, thank you for taking the time to reply!

Soil is supposed to be 6.5. Soilless is 5.9. Hydro is (I don't know, 5.4?). I don't ph my nutrients for soil. But, most people do (it sounds like). The common recommendation would be to pH your nutrient mix to 6.5. I would at least not ph-down it if you are doing that to get to 6. If you ph-up to 6, it's just a question of whether to ph-up to 6.5.

What kind of water do you use? Tap, RO? If tap, what is the ppm of the tap water before nutes? What is your runoff ppms? (runoff ph? I don't think that's too useful. But, if you have a ph pen, why not?).

1150ppm sounds awfully high for soil. I did 1000-1200 when using hydro nutes in soilless. In soil I do about 400-600. Your runoff ppms would tell you if you're getting salt buildup (especially if you had been monitoring it starting earlier.).

You're not doing *anything* different than your partner?

I assume this is your first grow(?). That's a pretty complicated way to grow. I would have suggested something simpler. But, it's good to see you're not doing the typical boutique "lineup" like most new growers do. You're thinking outside the box already. That's a plus. (You might not make it work. But, still, at least you're going to have some better understanding of what's going in the soil.).

The NPK ratio resulting from your mix would be interesting to see. (You'll get that from the spreadsheet.).It looks like a K problem, and some N. Probably a ph problem because they are unavailable at lower pH. But, probably from overfeeding and salt buildup (not your low-ph nutrient solution, although that would contribute.).

I'm using RO water. I skipped one nute because I didn't have it on hand but he said it shouldn't have cause any problems like this. When I said 1150ppm I was referring to the CO2 in the room, I don't check the ppm in the water.( I never thought about it) I do a calmag flush every 10 days or so to avoid salt build up. This is my second grow but close enough lol. I agree it is very complex but with the results he is getting it should be very much worth all the effort of nailing it down. I ran the mills line my first run and ended up getting some pretty bad nute burn due to false information from the hydro guys... I am going to start filling in that spread sheet now and see what I can figure out.

Also I'm using fox farms ocean forest soil
