My guess is nitrogen deficiency supposedly you should feed veg nutes 1 or 2 weeks into flowering just a little and week it off kinda

This can happen in flower. If the new growth is all looking good. And it doesn't seem to spread rapidly I wouldn't worry! Happy Harvesting!

Anybody got any idea with what's going on with these 2? The 2 larger plants are showing the signs of some stress on the fan leaves. Oddly enough the runt of the 3 is not showing these signs. Has anyone seen this before or can help me identify it?

Spots and dry leaves.
Help! I don't know what's happening to my Q1. There are spots on the leaves and some of the leaves are really dry. I didn't do the defoliation and i didn't LST so the plant is just going all natural. I feed her nuts from ATAI.

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto
Week 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Feuilles jaunes en floraison : carence malgré BioBizz AllMix
I have a pretty pronounced yellowing problem with the leaves of my plants after the end of the stretch. Almost all the plants are affected with big leaves that yellow quickly. I'm growing in BioBizz Mix soil and avoiding nitrogen because I'm getting burns.

Is this nitrogen deficiency? Should I change the soil?
Is this nitrogen deficiency? I've been feeding them and using pH Down but nothing changes (pH 7.2). Should I replace the soil? They're in CannaTerra mixed with Promix. I've got some FoxFarm Ocean I could move them to.

Yellow lower leaves
Guys/girls please help! Lower leaves have started getting yellow. I really don't know the issue. Is it of nitrogen deficiency? A lot of you have told me that 4ml of fish juice is a lot, so is there a possibility of nutrient burn? How can save her?
