started grow question 6y ago
My bottom leaves are turning yellow - Is this heat/light burn? Or maybe a nitrogen deficiency?

If you're not ph your water you will run into lockout problems. It looks like lack of nitrogen but could be incorrect ph range issuse or over watering issue. 👍🌱

Light green leaves and more
This just snuck up on my - don’t ask me how. To me it looks kinda like late stage something... what is it and what do I do? The colour is lime, stem is purple (but it’s been like that for the entire flowering period) and there’s some brown colour too.

Leaves still yellowing
I've been losing leaves to yellowing for awhile now, adjusted my water, feeding it seaweed, gypsum, fox farms big bloom, epsom salts, occasional blackstrap molasses and it is still occurring, is this normal and I'm just worried too much or is there something I'm not doing right?

Wondering if the amount/type of yellowing leaves is normal at this stage? Seems like maybe a nutrient defeciency (maybe burn? I dunno!) but given the stage of flowering not sure what should/can be done at this point. Have been providing ~1/2 dose bloom nutes (9-16-16). Thanks!

Maybe nutrient burn or?
My biggest plant has started looking a little sick, have a feeling it may be some type of nitrogen toxicity? Maybe it’s just got some nute burn? I have flushed it out and will leave it be for a few days and hopefully it perks back up

Gelbe Verfärbungen der Blätter
I discovered some strange yellowish discolorations (like camouflage) on the leaves of one of my plants. It's currently very hot in the tent with up to 30°C, otherwise I've been watering according to the BioBizz feeding schedule like I have for the entire grow. Currently: Temp. 28.9°C RH 35%-42%

Is she too far gone or can she come back?
Week 8. Biobizz Light Mix, Biobizz Grow, Biobizz Bloom and Top Max (1ml/L up to 2ml/L). Ph 6.2-6.5. Leaves started yellowing just over a week ago so I started to feed with CalMag at 0.6ml/L. Some of the top leaves are starting to die and new growth is turning yellow quickly.

Small yellow/brown spots. Rest of plant looks fine. 5 days into Veg
About 5 days into veg. 7 gal smart pots. RO water. No Nutes in the water so far. When transplanted I added a teaspoon of root microbes. Everything looks good and the green looks lively. Issue is there are few and subtle yellow spots. Not crowding. 1 or two on random plants.

My plants are turning yellow. I'm just days away from switching to the 12/12 cycle since I foliar-fed with Big One. If it's a nitrogen deficiency, how could I resolve the lack? Thank you very much for your valuable comments.
