WTF over/underfeeding/cold GG4

[Loc Dog]

I think I may have lost my GG4 strain, from not keeping a mother plant. I just went back to recirculating hydro with hydroton. Was using coir, but sick of bugs, every batch turning out different, and runoff numbers through the roof (in 600 PPM or 1.2 EC, PH 6.0, out 2000 PPM PH 5.0).

Using GH Flora series, which says for recirculating to use twice the strength of drain to waste coir. Was using the same, so might be underfeeding.

The cuts are from plants 3 weeks into flower, and it has been cold as shit. With thermostat on 72, some parts of house are 65.

Bottoms of plants look normal, tops are completely screwed. Just cut off all the tops. Pictures of full plants are in my public album. These are pictures of the tops I cut off. Basically wondering if over/under feeding, or extreme cold caused it. I know GG4 does not like cold.

They are revegging as a result of being taken in flower, they'll grow out of it but may take a while, sometimes months.

Peace

Thanks!! Really appreciate it man!!! Had one person say overfed, another said underfed. There were still some pistils on the tops, which I hacked off. I don't even care if they can not be grown out, as long as I can get cuts, and not lose the strain.

Do you have an opinion on whether recirculating hydro needs twice the feed of coir??? Almost everyone grows GG4 in coir, and feeds no more than 600 PPM (Hannah) or 1.2 EC. What would be first sign of overfeeding, tip burn??

I'd definitely let it grow out, I've done a reveg tuned out great just took a while, I cut down the root ball then transplant, took about 30 days before it came back around.

First sign of overfeeding would be tip burn just like you said.
