Purple petioles and cupping down
So, after watering with root+ 1.3ml/gal and amino extreme 1.4ml/gal and putting in a light that is double the wattage from the one prior it seems they got light/heat stressed. The purple petiole color could be phenotypic as it's striated in the stem too but I'm not 100%. Help?!

The stem of my seedling is starting to turn a purply colour? But the plant seems strong and healthy by looking at the leaves. I have been watering twice a day, app. 80ml each time from the bottom up and spraying about 4 pumps every 2nd water.

Pytanie ogólne
Hi there. I have a question. Why is there redness on the stems of the leaves on my 2 plants? Does anyone know what could cause this? Other than that, everything seems to be fine. Day 18 of auto gorilla cookies.

Hopefully I get back lots of "Don't worry! it will be fine" replies!
There is a brown resin coming from where the cotyledon leaves are/were. Is this something I should be worried about? It's no. 2, so she is the last one I should be worried about 🤨

My seedling is 9 days old now and growth is extremely slow. The stem is a red colour and the leaves are a slight yellow. This is my first ever grow and I just can’t figure it out. I would be grateful if anyone could give me some advice.

Whats causing the Stripes on my healthy plant?
My outdoor plant certainly appears healthy, but has developed beautiful burgundy Stripes on the Cola Branches. Can you explain what is happening, is this a genetic trait, or does it need something?

Help needed - harvest time?
Hi, I'm now in week 12 and I feel that after the flush my 2 vertigo stopped developing. They also have a lot of leaves with some mag issues. Not all the pistols are amber (70%). Also, the trichomes are not all cloudy. I'm not sure but I think I don't see changes anymore.

Purple stems and veins on leaves
Hey, plant looks heltlhy, she's getting bigger, but has purple stems and veins. What's your opinion on that? I had PH problem before, I watered her with low Ph water only and she got back to shape. Stems were purple before but now even veins on leaves are. Only few of them.

Deficiencies? Brown spots, yellowing and purple stems
What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.
