CRiSPrGrowanswered grow question 5 years ago
hey there Henvana, the burn marks on the sides of the leafs are from magnesium lockout and the burns on the tips are nutrient burns. This is not good my friend, you want to cut out all the nutrients and water with only plain water for at least 10 days maybe even 14 days. As long as your reduce the nutrients and feed with plain water with the plant should recover. Reading you i see "Plants are looking a bit healthier after flush though." keep that plain water coming , because the plants will like it lol. Hope this helps ! 🚀

I would flush, that is giving only ph water (make sure to calibrate ph meter), make sure you give enough water to have good runoff (10-15% run off), next watering start again with nutes at 1/4 strength and work your way up slowly. Just make sure you have a calibrated ph meter and keep ph in check!

To me it looks like nutrient burn at the leaf tips, and you were right to flush the soil! I would flush your soil an additional time and remove a significant amount of runoff. If you are noticing improvement after this, I would increase the amount of runoff during future watering to continue to flush any salts built up around the roots, and also decrease the amount of nutrients given generally. The plants otherwise seem nice and healthy, and the grow is looking good! 👍

I wouldnt worry about it too much, I would say perhaps a slight phosphorus or potassium deficiency. Or it could be a ph/lockout issue. Try giving some more bloom nutes maybe?

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Stains on the plantHey guys,
first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help

Insects, Mutation or related to my early nutrient burn ?Hey I noticed that one leave is looking like it has been eaten by something.. I checked every plant and also used yellow stickers, but can’t seem to find anything.
Is this related to insects or could it be something else ? (The plant had an early nutrient burn, but recovered)
