Cut back on the nutrients. Your original problem looks like too much phosphorus and then you made the issue worse by adding more.
Either way, 1300ppms is probably way too hot. Water with just pH'd water until you get your runoff down to 800 or so, then reintroduce your nutrients at half your normal strength. If the ppms in the runoff go up, then you're still feeding too heavily.

Hey there rollex , that's magnesiun deficiency, you can tell from the yellowing on the edges of the leafs. If you're already adding calmag so that means the root problem is the heavy light cycle. More light means more Mg required, but at some point the plant isn't able to absorb enough Mg , so it looks like a deficiency. You can reduce your light cycle as much as you're.comfortable with it should help, keep reducing it until the problem stops spreading. Hope this helps ! 🚀

Could it be just light stress? Seems to me that the discoloration only appears in the leaves straight under the light. Increase your lamp to plant and enjoy the recovery.

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.Week 13

High TDS and low ph runoff - Lockout? deficiency?Struggling with some bad soil (beginners mistake). I water with dechlorinated tap water at around ph 7.4 and 400ppm (not feeding yet). But runoff ph is 6 and around 1000 ppm.
Am I dealing with a N-lockout? why such a ph difference and high TDS value?

I have been having issues and believe its the lightsToday I moved my light closer from 60cm(thought my light would be too strong at 600W) to 30 cm after looking at the specs
PPFD: 30cm-564μ.mol, 60cm-146μ.mol, Is this the correct thing to do?
What can I do to improve my set up?

Leaf discolorationMy cat knocked over my grow light onto my plant, since then, she has developed discoloration on almost all the outer edges of her leaves. Is this stress? Will it go away or get worse?
It's been about 12 hours since I righted the light. There was no discoloration 24hrs ago.

Leaves with yellow spotsWe have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).

Crispy dry margins on the upper leaves. Please see detailed pics through week 5 of flowering. Pics from different days are available.The younger plant was showing what I thought to be P and K deficiencies on the leaves. Growth stopped too. Increased its nutrient amount 3 days ago (bloom-grow-acti). Since then I observed some bud growth but the problem on the upper leaves continue. Any ideas?

Low PH runoff, dealing with deficiency due to low soil PH. Added lime and PH went from 5.4 to 5.0 after watering. How to raise it safely and quickly?I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.
