Nutrient issue
Greenpoodlestarted grow question 2 years ago
I think i have a nutrient issue. Any ideas on what it could possibly be? All appearing on older fan leaves. New growth seems fine so far

I agree with Grey_Wolf in that you're overfeeding them - the clawing and nute burn is coming from your grow nutes - they're getting far too much nitrogen at the moment!! If this were my grow, I'd simply get rid of the Bio-Grow altogether (it's got an NPK of 4-3-6) since everything else you're feeding has some nitrogen in it (heavens - even your calmag has 2.6% nitrogen!). I'd also go to a water/water/feed/water/water/feed type of schedule. Make certain you're getting good runoff when you water so you're helping to clear the salts out of her as you go along. Your damaged leaves won't recover but if you see continued, expanded problems, I'd do a complete flush ending with 1/2 strength nutes (minus the BioGrow).
Good luck!

@Greenpoodle your overfeeding them mate
a lot of those leaves have a claw like appearence that coincides with nutrient burn
thats seems a lot of additives to be using in soil what is the ph of your soil
ideally it should be around 6-4 to 6-5
the heat issues from the lights is also causing issues but the main thing is the overfeeding
try cutting back to just the bio bloom stuff and the cal mag after a couple of days of plain water
get another fan in there if you can

Sick plant, could be temp, nutes, too much water?Leaf tips looking burnt and wilting in flower ... keeps getting worse no matter what. pH 6.8. Raised light. Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Healthy?Sie wachsen zur Zeit sehr schnell allerdings haben manche Blätter Flecken wie man sehen kann. Die ersten Wochen habe ich leider mit einem zu hohen Ph Wert gegossen (ca 8) dies habe ich jetzt aber angepasst und sie bekommen ihre 6,4.Vielleicht Nährstoffmangel? Bio Grow hinzufügen?

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

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. More info in my report.
