What could this be? Deficiency, or pests?
GWSD82started grow question 4 years ago
White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?

Yes my friend, you have been running at the top level of ph for soiless grows so the 6.2 in the runoff is actually set for taking more p and k not nitrogen. Get your ph down to 6 or under in your runoff. Just feed at 5.5 until your ph runoff drops and things will get better. When you switch to flower, and you see flowers forming, start your girls at 700 ppm 1.4 ec and 6.2 ph for early flower, mid flower 6.3 ph and 1.6 ec and for late flower back down to 1.2 or 1.4 ec. Cheers

gave it a minor dose of cal mag plus just in case this is a developing deficiency. It has three nodes but it is very small at approximately 1.5-2 inches. The pattern may be genetic?

Is it infected?Is it infected, like mildew, or has it just some nutrient problems in the beginning? And the leaves form is just the genetic i guess?

Bright green spots and wilting.I seem to have some wilting with some bright green spots on some leaves. I just potted up and she's at 20DLI, 0.6 VPD, 790EC @ 6.0pH. 75F, 71%RH, autoflower in canna coco pro plus.I turned my fans down a little since they were a little aggressive, so I'm hoping that's the issue.

Leaf edges a bit yellow and now some yellow mottling. Signs of the same problem?Leaf discoloration now on a few leaves.... Could this be continuing signs of an imbalance caused by switching nutrients for the first week of 12/12? Please see my previous question about yellow leaf edges and Sciolistic_Steve's answer. I'll be switching nutes tomorrow anyway...

Help Identifying Ailment! BlackBerry Auto on week 6! Nutrient deficiency? Cant find anything online similar.This is my second grow since switching to hydro. Growth has slowed a lot. Leaves are getting brown spots and almost look like they're being eaten but no pests can be found. No root rot, I dont think I'm over watering them. Since I started hydro it's been a real challenge.

Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)
