Have you done a proper diagnoses. Check your runoff ph and ec levels. Feeding cal/mg every time you feed is not needed. Once a week should be sufficient. Adding cal/mg all the time just overloads it. Especially if your ec is already creeping up on you. Next watering check your values, get them back in their proper values. Cheers

Yellowing leaves Hi Growmies, im in week 7 of my flowering cycle, my leaves have started yellowing between the veins before turning brown and dying from the tip inwards. Is this a calcium deficiency? Or is it natural dying from the end of flowering cycle or something else? Please advise thanks ✌️

Lowest leaves turned yellow After a very hot and sunny day (about 37°C) I noticed that the lowest leaves turned yellow. Is this a sign that I should use more Terra Bloom? If so, how much more should I use?

Yellow leaves on plant My tallest plant has been displaying signs of deficiencies/abundances of nutrients. I am worried about the yellowing leaves that have been getting progressively more pale for the last week. Is this a light, ph or nutrient issue? Week 6 of flower right now and N has been cut down.

My Royal Creamatic has the edges of their leaves pointed down, loosing soil and some yellowing in the older leaves. I've tried to use google but there were many opinions about this. Have the feeling that I should just give ph water for now. Any ideias/advice? Thanks

Triple-leaf Speedy Chile: what is growing there? Why becoming yellow?My triple-leaf Speedy Chile (see also week comment for more info): 1. The 3 cotyledons have become yellow. I also see on lower leaves slightly some yellow tips. Nutrient deficiency? Underwatering? 2. What are the small leaves coming out of soil. Another plant? Should I remove?

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.

Wondering if the amount/type of yellowing leaves is normal at this stage? Seems like maybe a nutrient defeciency (maybe burn? I dunno!) but given the stage of flowering not sure what should/can be done at this point. Have been providing ~1/2 dose bloom nutes (9-16-16). Thanks!

I can not take out of the tent to the darkness more than 4 at once and wanna hear your suggestions before I go with yellow sugar leaves or some amberish :D I read something about harvesting immediately (not to crap the flower) when sugar leaves start to turn yellow and I have some! On the other hand, I saw some trusted videos that has some yellow sugar leaves. I want to ask you if you have any experience with this issue?
