Also, I have made many batches of aloe vera foliar spray. Just use a nutrabullet or blender and a few chunks of aloe leaves cut up and dropped into the blender, uses some water to dilute it and you will have a beautiful green foamy spray, I use spray usually a few weeks before flower. It puts a nice coating to protect the plant from certain bacteria and harmful rays from the lights.... Check out homemade aloe foliar spray online. I bought a plant 4 years ago and have uses that plant for several grow.cycles and the plants always responded well.

I would also look into Foop, there is a foliar spray. It claims to help with most nutrient deficiencies and has no harsh chemicals. I've been using it for many grows and I have even nuked CERTAIN plants during the lights on with no issues ever, LIKE burning or any negative reaction....I would suggest looking into Foop, it honestly does wonders. I'VE NEVER HAD A PROBLEM USING IT.

Have you hit them with any cal/mag?

Listen to what you've been told by @GrowingGrannie. First check the pH of the solution you give and of the soil you use. Try to figure out if you've fertilized with too much nitrogen. Increase humidity a bit to 45/ 50% Usually calcium deficiency starts during flowering when the plants really need it, so if it's all ok with ph/ec and the amount of nitrogen you use is probably just that.

Yup. She's getting a calcium deficiency - but before you throw a bottle of calmag at her, you have to figure out why this has happened. If she's been given too much nitrogen or the nutes and salts have built up in the soil, that will create a lockout of calcium and the plant will not be able to get to any calcium you may give her. Same thing with the pH - if it is not at a good level, that will also prevent the plant from accessing the calcium... pH should be between 6.0 and 6.5 in a soil grow. If those things are ok, then she just needs more calcium but generally any decent cannabis nutrient is going to have sufficient calcium in it so that calmag is not needed. If you had a diary, it would be a fairly simple matter to tell you which problem you have and what you should do about it. Diaries help us help you... please consider starting one for this grow. Good luck..
