First Grow - Leaf Problems

[mobius42]

I have made lots of rookie mistakes, bad pH, temps, and nutes too early, but felt like I had things under control until tonight. I flushed the system with clean pH'ed water last week to clean out the extra nutes from overfeeding and put in half strength nutes on Saturday. I noticed some of the newer leaves have started to curl under now and wonder if maybe I was too quick to cut back on the strength. Leaves feel very dry and I have been spritzing with tap water twice a day. There also appears to be some buildup on the top feeder, but I don't have hard water and unsure if this is just typical for hydro.

Air temps range from 50-85, but water temps stay around 70 with the heater I picked up last weekend. Humidity varies greatly from 5% to 50%. The Blue Lab pen I picked up this weekend can't seem to hold calibration and need to return it, so I have been sticking to the drops and keeping pH at 5-6. I am using GH Flora series nutes at 2.5 ml/gal Gro, Micro, and Bloom. I was following the chart to literally at 10/7.5/2.5 two weeks ago and was when I noticed the lower leaves starting to burn. Under a 1000w MH at about 30" height from plant.

Sorry for picture quality, camera seems to freak out a bit under the light. Any help would be greatly appreciated.

You should really try to stabilize the environment in that area if you can.

Those are HUGE swings day to day..

Also.. fwiw.. soil is much easier, lol. And imo, will give you the best results possible.

Keep things as close to nature as you can. Just my two cents, of course.

Try skipping the nutes for a couple days. See how they react. Seems a bit early to be using nutrients already.

I'm also in Nor.Cal. Weather here is pretty much perfect year round, so dirt is a snap.

Love it.

OP - skip the nutes and let them snap out of whatever is going on. If you had/have some type of uptake issue continuing to give them nutes isn't gonna help anything.

They'll live w/o them for a few days.

In his OP he said it's a 1k halide. Raise it up a bit more than where you have it and ease off the plant food. They look overworked.

This was just one more reason why I always avoided hydro. Force feeding nutes to plants that young seems so backward to me. I generally don't touch the nutes save for a tiny bit of b1 for at least 2 weeks to start. Oh well, lol.

Thanks all for the input. I am sure I am just overly nervous, but the cupped leaves seemed odd and I didn't see anything the really fit in the sick plant thread. The plant is actually 4 weeks old today and really only started taking off in the last week or so.

cutting back on nutes was a good idea, the damage caused will probably be permanent leaf wise, but it can be overcome with new growth of new leaves. always caution on the side lower nute levels, the gals will be happy in veg stage with the minimum of nutes. the levels recommended on the labels are usually more directed towards getting people to use more of their product IMHO

100% agree on everything
