Hoping you can possibly help with my ongoing issue
Some basic info below:
Media - soil FF Ocean forest
2x4 & 4x4 indoor grow tent (6 plants total)
250 watt Viperspectra 1500 Pro LED & Viparspectra KS5000
Fabric pots - 5 gal
Originally spring water for first 8 weeks, changed
this week to RO water.
Indica plants
Fox Farms Trio nutrients, Cal Mag, recharge
Carbon exhaust and clip on fans
Plants in 8th week of veg
Watering/feed at about 1.25 gal per plant
Ran 6 weeks veg without flush and PPMs in runoff got as high as 1800-2000 ppM, runoff ph around 6.0- 6.25… Leafs started to yellow with green veins and then brown spots.
After flush with sledgehammer, ppM down to 550- 700. Did a feeding at next watering and PPMs up to 700-900 runoff after feeding. Did a watering with calmag and fish shit 3 days later and PPMs at 1000-1200. PPMs going in are about 600-700.
Plant do not seem to want to move from lime green to darker green and PPMs continue to rise concerning me that they are not up taking nutes. I talked to Fox Farm and they said don’t go by runoff, do a slurry PH which I did and came out with 6.4 ph. I have been wanting to move these to flower but concerned that they will continue to degrade.
Interesting to note that internal and lower leaves are nice dark green.
A couple of questions:

A couple of questions:
- Do you think the plants are stilled locked out and require another flush? Is only been 2 weeks since last flush.
- Am I too concerned with PPMs and not feeding enough so perhaps that is why they will not recover. When feeding, only 1/2 Trio recommended.
- Should I top dress with some dolomite lime to increase the soil ph ?
- Could high humidity in late veg cause some of this problem 60-75%
- I have been delaying flipping to flower for 2+ weeks and concerned that the what I hope to see in improvement may not ever get there…. Do I flip or wait more?
