Sick plants! Need help! Stems are turning purple!

[tokerace]

looks like overfeeding and heat stress to me. I would cut the temp down to 72 for awhile. Maybe give them a little B. I quit using GH flora nova...all I had was probs.

Really does look like a heat problem, and tokerace is right about FloraNova. I just cut everything they to use in half. Also your suppose to use regular water between every feed. You cant just cant give ferts. Give it time to use the nutes and ferts that it has and then feed again. I feed nutes every other feeding

Hey guys I really needed help so if you guys would help me out...

My stems are turning purple, and any leaves that are connected to the purple area seems to be withering. Here are some pics. The top is green and its flourishing. I run about 2.5ml/gl of GH Flora Nova Bloom and Grow. i also use liquid seaweed and cannazym. Lately its been doing good, and still is, but I want to know whats causing this? THis happened recently.

See the yellowing on the bottom but not the top, and how the yellow areas are connected to the purple?

If i had to guess the drip system maybe splashing a little bit on lower leaves will cause them to decay like that. purple stems seem to be normal thing more so on sucker leaves. I would recommend using better water then distilled. Keep in mind you made a few changes in system. changes = stress good luck
