Dilemma is lower leaves yellow and die off and or the tips instantly burn off. I have tried adjusting the nutes and ph slowly/ day by day to correct problem. Watering once a day currently. Ph started at 6.4 and lowered to 5.8 eventually.

Growing in coco coir 50% perlite- 3rd season on substrate. Using fabric smart pots. Outdoors. Temps are 70-95* roughly 50% rh

Unknown strains from friends seeds.

Mixed per 5gal
Ro water 200tds .43 ec
Ph 5.8
30ml calcium nectar for the gods
1 tsp epsom salt
17.5 ml flora micro
25ml flora bloom
1/2 tsp unsulphured molasses
4ml heavy roots hormones
4ml rid-x enzymes
15ml mad farmer nuts
4ml silica blast

46 days old btw. Cheating veg with a supplement light for 19hrs total.

Will have to clean the pot pans and check runoff tomorrow morning before next watering.

So currently my feed is at 5.9ph, 1.09 ms, 785ppm. Runoff is 6.29ph, 3.8ms. The only way I see the runoff ppm being so high is enzyme/ bacteria activity??? Plants are about 4 days into flower.

Did you recently switch to Flower nutrients?
Looks a bit like N defficiency to me.

Same n dominant veg formula. Havnt adjusted lately. But i have started watering 3 times more frequently dtw, after doing this the rest of the leaves turned allot darker green. Having a hard time believing N deficit. Could it be a P defict or some kind of toxicity? Maybe the enzymes are breaking down old coco rapidly causing the high ec runoff/ toxicity?

Old leaves may never recover. It's the new leaves that matter.
