Tombonestarted grow question 4 years ago

Is this sign of deficiency, to close to light, or toxicity? If so any ideas how to fix? Thinking of attempting a flush later??

You got multiple issues here. I would start with substrate ph. What is run off. I imagine it is out of range causing deficiency. Your light should be about 20 inches away from top of plant. If for some reason your ph checks out. Which I am sure it won't. You have potassium deficiency, the leaf is sulfur deficiency actually. So I got my money on your ph is wrong. Needs to be about 6.2. Test with calibrated tool. Run off to. Good luck. You get the ph right and new feed, should spring back. Good luck and happy growing. 🌲🌲🌲👊💨💨💨

Hi ! Ja, ze heeft net te weinig voeding, heeft last van de hitte en kan volgens mij meer water gebruiken, als je niet veel geeft. Pas dit aan en het komt goed 🙂 Hopelijk kan ik helpen. Veel succes met groeien!

Leaves turning light green -- yellow (after 12h day/night rhythm)Since I started with 12h daylight/dark rhythm a lot of leaves started to turn yellow (older and lower ones first, some branches turned red). What I did: PH value=6.5. I added CalMag--no effect. I flushed the soil --no effect. Do you have any ideas? Thx green thumb-friends 👏

Why my plant is in shock i fixed the ph of watering .I suspect of this reasons:Heat wave/changing phase to flowering / nutrient locked/ over watering/. In I lowered the ph of watering from 6.8 to 6.0 but this plant is still is shock and wont grow like others. Could it be a sign of changing phase from veg to bloom ? 3 weeks ago my first plant went to flowering and did the same color fading. Now that plant has good color

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Burning Edges/Yellowing and Drooping?The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!
