Grow QuestionsCalcium or Phosphorus Deficiency?

Calcium or Phosphorus Deficiency?

StuG69started grow question 3 years ago

One of my 3 Cream & Cheese has upper leaves on 3 stems/colas per the pic. The lower leaves are OK, the other 2 plants are fine. Thought calcium at first as phosphorus is more lower leaves? Maybe just add CalMag? Thank you so much!!

Yep, fairly typical example of cal/mag deficiency - symptoms of calcium deficiency in pic one and magnesium in pic 2. Damaged leaves will not recover, but adding more cal/mag asap will stop it getting too much worse. Remedy won't happen overnight, but it should pick up in a week or so. Generally, what is now showing in the leaves, is a reflection on what was going on in the soil 2 weeks ago. Remember to give all your plants cal/mag, preventing problems is better than curing problems! Hope this helps, Organoman.

Yellow Leaves Autoflower Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. 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?)

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.

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...
