Leafs yellowing
What can this be? It happened in 1 day. Is plant asking for nuts? I added only water for 4 days because i was afraid of been giving to much nutrients. Could be a pH problem?

Leaf problem and purple stems
Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer

Yellowish Spots on Fan Leaves
The fan leaves on one of my plants are getting yellowish spots. I noticed it yesterday and checked the pH and I was at 5.0. I corrected it to 6.0 and 24 hrs later still 6.0 but some of the larger leaves are starting to show yellowish spots as well?

Nutrient deficiency
What kind of deficiency these leaves are showing? Can this be lack of nitrogen? I am using a lower amount of BioBizz Grow these days (1ml/L), passing to BioBizz Bloom and Top Max as they are in the middle of the flowering stage. In case, should I integrate with more BioBizz Grow?

What could it be?
I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.

Seedling Light-burn or Toxicity
Hi growers! Is this Light Burn, or nutrient toxicity from nutrient dense soil? 2 Mars Hydro TS600 lights at 27" from seedling. PH 6.3 misting soil - RH is 75-80%. - Temp is 77F No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

Yellowing leaves and nutrient lockout. How do I fix this? This has been a long time problem. Definitely overfed for the first 3 weeks of flower.
Lemon Cherry Cookies locked out for weeks. She's yellowed up big time. Took in less than a quarter gallon water yesterday and a half gallon today. But then she had a higher EC and TDS before adding plain pHed water both days. After topping off it went back down. Check my diary.
