Runoff water was at like 3 for both plants, i've been using ph down to lower the water ph from 7.8 to like 6-6.5. First two pics are of a 8 week old skunk plant that has some yellowing leaves and brown tips. Second two are of a plant that i think is around 5 or 6 weeks that has brown tips that are starting to curl down, also something I thought was from heat (shown in pic 3.) Im guessing ph lockout? let me know. peace.

what are you using for ph testing, if a meter, you need to get the chem test kit from the pet shops, faulty meters are the cause of many ph problems and the chemy test kit are your backup/failsafe

your plants are going into ph lockout, deficiencies are showing as well as leaf twisting

your using too much ph down....lower to 6.8 from this point

flush to get the acid out, when your reading 6.8, flush 1 more gallon with 50% ferts

Im using a pool testing kit with the dyes. I actually saw your site and did exactly that, flushed and then last gallon with 50% nutes. Should i just use the correct ph water to fix this or use something to raise the ph in the soil?

since you have flushed already , take a wait & see till next watering, water enough to take another runoff sample to be certain you have your PH within acceptable limits if not repeat your flushing till the soil ph is correct
