Looks like a possible deficency crawling in. She's looking light in color also. Try feeding with a higher nutrient dose. 🤘😤

Problem in 5 Week of Vegetation
Now in the 5 week of vegetation. The plants are Tropical Gelato cuttings. Everything was great until recently. They looked great. After another light fertilization, the condition of the plants continued to deteriorate. Soil PH value is between 6 and 7. Can Someone help?

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto
Week 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

What do you think the problem could be?
There’s something going on with some of these plants and I can’t seem to identify the problem so far. I have been doing a lot of research and I’m in a process of elimination at the moment but the plants growth hasn’t been affected. I will continue to try treat the problem.

MicroScrogger
I'm starting to notice yellowing of leaves almost daily now on a Critical XXL scrog grow. She is 5 weeks into flower, had a rough (cold) start, and has always been a bit stunted. I was worried I'd overfed (3ml / l biogrow) so scaled back for 2 weeks. Is this normal?

Possible calcium def. or other issue affecting leaves and buds
Is this a calcium issue, and if so why is it spreading to this one bud in particular? There are four photos of the effected bud, as well as a few shots of unaffected buds to compare. Also have spotted leaves that look like ca issue but not sure why its spread to the one bud.

Leaves turning yellow and dying
I have a plant that gets a lot of rust spots, even though I give it CalMag once a week. That plant also started getting a handful of leaves that turn yellow and fall off. Is there a nutrient I'm missing in my regiment? Should I do CalMag every watering for the rust spots?

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!
