Leaf tips yellowing. Overwatering? Or nute burn?
Freebyrdstarted grow question 2 years ago
I recently flushed my soil with water that was PH 7 (my soil was a bit too acidic). My question is: are the yellow tips and browning due to the overwatering from the flush? As well as stripping the soil of its calcium? Thinking of giving them 3-4 days before watering with calmag

Flush is quite stressful for the plant.
when it's on the tips like that all around before anything else, it's likely a K-deficiency. If in soil it depends on how much nutes you leached out of the substrate.
always try to avoid flushing. if pH is off, pH-adjust next fertlized water irrgation and get some extra runoff or if not a fertilized irrigaiton start with a little extra runoff before going all out with a large flush.
If pH was way off it could have locked it out if too far below 5,5. oh fuck i wrote all of this and i'm gonna get a banned message. will copy and paste to DM

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?Leaves. Tips - Burnt

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.Leaves. Veins - yellow between

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.Leaves. Curl up

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay.

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.7 months ago
