Papa_Tanswered grow question 4y ago
I wouldn’t wait until your next watering and give it a good balanced PH. If you flush you risk starting to chase mega problems. Your plant looks nice right now. Yeah ok a little nute burn but she’ll recover and your new growth looks good so I would just keep pushing the way your are right now.
I would wait a bit before doing a drastic flush. Just monitor it for now.
Mr_Death_himselfanswered grow question 4y ago
Don't up your ph, lower your nute mix just slightly. Upping your ph will block out nutrient intake all together and that's not good. Flush with standard 6-6.5 for your medium but be careful not to do it for gor too long as it may yellow from lack of nutes

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc.
I believe this may be nutrient burn?

Help with diagnoses leaf yellowing and yellow spottingCan anyone help me in the right direction on what the plant is telling me she needs. I'm getting yellowing on lower leafs and spotty yellowing on upper leafs. I thought maybe light burn for spotty yellowing and raised light a few inched with no change. I appreciate the help!

What to do? Leaves are getting worse.Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?
