Are you flushing ? It's just the natural fade of the plant as it comes to the end of its cycle in flower. Nothing to worry about , it's just a lack of chlorophyll in the leaf as she fades out.

Nutrient Help possibly needed
For my first grow I have kept things fairly simple. I had issues with my soil PH which stopped nutrient uptake but seems to have now resolved that for the most part. Are there any other nutes that are recommended to help bud production or am I ok with what I have now? Thanks

Nute Lock??? What would you do?

Hello everyone, I have 4 plants in a 3x3 area under three of these lights - https://amzn.to/2MhseVH 360w all together which is what I expected to use during flower, I didnt realise that you dont need to use as much during veg, all plants have had to be flushed with EC's at 10

Calcium deficiency impossible to fix.
I cannot get ahead of calcium deficiency in spite of adding calcium nitrate base with extra cal-mag daily. I just keeps getting worse and worse... any advice? Hydroponic RDWC, day 29 flower. It’s fine in veg, once they hit bloom, can’t keep them healthy.

Halb gelb, halb grün
Meine Pflanze zeigt aktuell leichten Kalium Mangel. Aber irgendwie nur auf eine Hälfte der Pflanze. Die andere Hälfte sieht gut gefüttert aus. Kann mir das jemand erklären? Also warum betrifft der Mangel nicht die komplette Pflanze?

Nitrogen Toxicity?
Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Cutting damaged leaves away or not?
Hallo, I have some spots on leaves due to calcium deficencie and it has stoped spreading above leaves by adding calmag to the nutrient solution. We talk about 2 single leaves per plant (max 3 leaves). Should I cut them of because they need energy to recover or does it not care?

PH drops every 4 days
I'm losing PH control 4-5 days after feed. PPM drops to 200-300 and PH drops under 5. I flush the res and add new solution every 5 days because this is what works to stabilize ph. It can hold ph for 4 days before I lose it again. You think I'm under feeding?

Magnesium Deficiency ? How can I fix it ?
got a little deficiency (maybe burned? but I think not). I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

K deficiency almost wiped out this plant. What do I do now?
I’m somewhere between 2-3 weeks until harvest time should be. It’s day 80 from seed on this autoflower. Had a bad potassium deficiency that I didn’t figure out quite in time and I’m not sure if too much damage has been done. What should I do?
