Second ever grow - Easy Bud on a budget

Check ph. I could be off and not allowing the plant to uptake calcium magnesium or iron. I had this issue when my ph pen was off.

Thanks both for the responses, much appreciated. I did switch from Bio grow to bio bloom only during flowers so you’ve probably nailed it on that mistake I’ve made. (It’s been a learning grow all round!). I don’t *think* it would be calcium deficiency as we’re in a very hard water area. @GrowingGrannie re:trichs are you looking in my diary or the photos in this question? The photos posted in the question are from some lower popcorn buds near the bad leaves. The upper buds I think are nearly ready. Most pistils brown and curled in, mostly cloudy trichs with a few ambers forming. Like I say a learning grow using LST and new lights for the first time - so not expecting much but looking forward to chopping and going again with everything I’ve learned and the great tips from people on here!

If you're going to add nitrogen to this grow, ONLY do it by adding some Tiger Bloom to your feed... it's got a small amount of nitrogen and I like to combine it with Big Bloom (having cut out Grow Big altogether). But I don't think that's your problem at all... I think it's calcium deficiency. And from the look of your trichs, you've got 3-4 more weeks to go so it IS something you should address. I'm not seeing any info on the PH level and so I would ask if you check this... They look like they could benefit from some calcium but I've not found any problem with calcium deficiency using your nutes (and they are exactly what I use)... Calcium is absorbed when the PH is between 6.2 and 7.0... outside that range, you can give it all the calcium in the world but the plant won't be able to get at it... so double check your PH. If it's in the right range, then you can add some calmag once a week... Fox Farms sells a good calmag.... but DEFINITELY check the PH of your solution when you add it because it does a number on the PH levels and you'll have to adjust... And btw, as far as PH is concerned, in order not to have any OTHER problems with nutes and micronutrients, try to keep your PH to 6.2 or 6.3... it is the "sweet spot" Good luck!
