I just have it mounted to some 1/2" plywood.

Rust spots on the leaves is indicative of a calcium deficiency.So everything has been going well. Thinking I’ll flip this weekend, but now I’m seeing a few plants show stress and I don’t know if it’s nutes or light.
I’m seeing some leaves yellowing and some tips yellowing. Any insights?View attachment 916978View attachment 916978View attachment 916980
Just a little tip. I'm assuming you have the fan set up to exhaust air out of the tent. It will be much more efficient if it’s exhausting air from the top of the tent, not the bottom. Hot air rises so you get better air flow exhausting from the top of the tent.
Cool. That should work fine.air cooled tube - Its pulling air from the middle top of the tent. Its gotta drop down to floor level at some point.
But ty. :)
That’s what I thought. So add Cal/Mag to the reservoir.Rust spots on the leaves is indicative of a calcium deficiency.
I have this for an 8x8 tent. The only weight I have directly on the main polls is a 30 lb light. I’m supporting the filter with 2 cross bars from the old 10x5 tent.Just a little tip.

So if not Cal/Mag to the reservoir, what? Foliar spraying?IMHO while it is a calcium deficiency it's not from lack of calcium. Calcium is taken up passively as direct result of transpiration. Look at how swollen your leaves are. This is a transpiration issue not lack of nutrient issue.
Just my 0.2 cents I think I mentioned before do not add anything to self ph adjusting nutrients but it's your grow man. Sometimes you just need to learn the hard way.
Again just my opinion.
He's having the exact same issue I had with those nutes.IMHO while it is a calcium deficiency it's not from lack of calcium. Calcium is taken up passively as direct result of transpiration. Look at how swollen your leaves are. This is a transpiration issue not lack of nutrient issue.

Also your damaged leaves will continue to get worse... They will not get better so it may appear to get worse but if it's not spreading to new leafs then you are good
The leaves with calcium damage are not going to get better... Are you 100% sure it is spreading to new leaves.... Not just the old ones that are damaged looking worse.So if not Cal/Mag to the reservoir, what? Foliar spraying?
I don't recommend going against the advice of these experienced growers, but I added cal / mag in a half dose to mine and they perked right up and stopped "rusting" overnight, imo those nutes + RO water was a bit on the acidic side and all that happened for me is a slight raise in PH (closer to the ph id like to see). Are you using the nutes full strength?So if not Cal/Mag to the reservoir, what? Foliar spraying?
Yes this is more common than most think. I tell ya I can't say it enough... The nutes get fucked up and you get deficiencies when you add calmag and or ph up/down and they need to be used with RO water. That's it measure ppm don't look at ph. Now there I have also seen issues with running it at low ppm so I would not go under 400ppm.He's having the exact same issue I had with those nutes.
Yes. I’m for sure seeing yellow tips on some new leaves. Also some reddening on a few stems. The mottled yellow is only on bigger older fan leaves on a couple of plants. It’s not too bad right now, but I’d like to nip it in the bud before flipping.The leaves with calcium damage are not going to get better... Are you 100% sure it is spreading to new leaves....

If it's older growth it's either magnesium or very old calcium damage. Calcium is not very mobile. Tip burn is likely high ppm or since your in coco letting it dry to much. But @Enforcer is the guy you want to talk to about feeding. The red on stems is of no concern and is usually from light or strain genetics or both. Purple can be low temps and is indicative of phosphorous deficiency but usually unless you see stripping in the stock and it carrying into the leafs it just genetics.Yes.

I don’t think the coco is too dry. Runoff EC is 1.3,If it's older growth it's either magnesium or very old calcium damage. Calcium is not very mobile.

@Enforcer is the dude you need to talk about feeding schedules for coco. My feeling is the more often the better once they are established. Keeps the ph and ppm in the root zone stable and prevents build up.I don’t think the coco is too dry. Runoff EC is 1.3,
so I think that’s good too.

18 degrees Celsius, so 65 Fahrenheit.What temp are your nutes at when you feed the plant? Winter time, me and another guy had that issue.
